Python Coding Challange - Question with Answer (01290525)

 

Understanding the Loops:

1. for i in range(3):

This is the outer loop.

It runs i = 0, 1, and 2.

2. for j in range(2):

This is the inner loop, and it runs inside the outer loop.

It runs j = 0 and 1 for each value of i.

 Iteration Breakdown:

Let's see what happens in each iteration:

i j i == j? i * j Printed?

0 0 ✅ Yes 0 × 0 = 0 ✅ Yes

0 1 ❌ No – ❌ No

1 0 ❌ No – ❌ No

1 1 ✅ Yes 1 × 1 = 1 ✅ Yes

2 0 ❌ No – ❌ No

2 1 ❌ No – ❌ No

 Output:

0

1

 Explanation Summary:

The code runs a nested loop.

It checks: "Are i and j equal?"

If yes, it prints the product i * j.

Only when i == j (i.e., both are 0 or both are 1), the condition is true.

1. Import Required Libraries

import numpy as np

import matplotlib.pyplot as plt

from scipy.integrate import solve_ivp

numpy for numerical operations.

matplotlib.pyplot for plotting.

solve_ivp from SciPy to numerically solve differential equations.

2. Define the Rössler System Differential Equations

def rossler(t, state, a=0.2, b=0.2, c=5.7):

    x, y, z = state

    dx = -y - z

    dy = x + a * y

    dz = b + z * (x - c)

    return [dx, dy, dz]

Python Coding challenge - Day 514| What is the output of the following Python Code?

 

Code Explanation:

Function: reduce_to_one(n)

This function implements a process related to the Collatz conjecture — it reduces a number n down to 1 by following these rules recursively, and it counts the number of steps taken.

1. Base Case: Check if n is already 1

if n == 1:

    return 0

What it does:

If the input number n is already 1, the function returns 0 because no more steps are needed to reduce it further.

This is the stopping condition for the recursion.

2. If n is Even

if n % 2 == 0:

    return 1 + reduce_to_one(n // 2)

What it does:

If n is even (i.e., divisible by 2), it divides n by 2 and makes a recursive call on this smaller number.

It adds 1 to count this step (the division by 2).

The function keeps going until it reaches 1.

3. If n is Odd

else:

    return 1 + reduce_to_one(3 * n + 1)

What it does:

If n is odd, it applies the formula 3 * n + 1 and recursively calls itself with this new value.

Again, adds 1 to count this step.

4. Example Call and Output

print(reduce_to_one(3))

How it works step-by-step for n = 3:

Step Current n Action Next n Steps so far

1 3 (odd) 3 * 3 + 1 = 10 10 1

2 10 (even) 10 // 2 = 5 5 2

3 5 (odd) 3 * 5 + 1 = 16 16 3

4 16 (even) 16 // 2 = 8 8 4

5 8 (even) 8 // 2 = 4 4 5

6 4 (even) 4 // 2 = 2 2 6

7 2 (even) 2 // 2 = 1 1 7

8 1 Stop - 0 (base case)

Total steps taken: 7

The function returns 7.

Output:

7

Python Coding challenge - Day 513| What is the output of the following Python Code?

 

Code Explanation:

Function Definition

def tricky(a=[], b=0):

Defines a function tricky with:

a: A list with a default value of [] (mutable object).

b: An integer with a default value 0 (immutable object).

Key Point: The default list [] is created only once when the function is defined, not each time it's called. So a will retain its state between calls unless explicitly passed a new list.

Append b to a

    a.append(b)

Adds the current value of b to the list a.

On first call, a is empty: [], and b is 0, so after this: a = [0].

Increment b

    b += 1

Increases the value of b by 1.

Now b = 1.

Return Tuple

    return a, b

Returns a tuple: the updated list a and the incremented value of b.

First Call

print(tricky())

a is the default list [], b = 0.

a.append(0) → a = [0]

b += 1 → b = 1

Returns: ([0], 1)

Output:

([0], 1)

Second Call

print(tricky())

Here's the tricky part:

a is still [0] from the first call (because the default list is reused).

b = 0 again (default integer is recreated every time).

a.append(0) → a = [0, 0]

b += 1 → b = 1

Returns: ([0, 0], 1)

Output:

([0, 0], 1)

Final Output

([0], 1)

([0, 0], 1)

Python Coding challenge - Day 512| What is the output of the following Python Code?

 Code Example:

Function Definition

def memo(val, cache={}):

def memo(val, cache={}):

Defines a function named memo that takes two parameters:

val: A value to be processed.

cache: A dictionary used to store previously computed results.

Note: Using a mutable default argument (cache={}) means the same dictionary persists across function calls. This is key to how memoization works here.

Check if Value is Cached

    if val in cache:

        return f"Cached: {cache[val]}"

Checks if val is already a key in the cache dictionary:

If it is, return a string showing the cached result.

Example: If val is 2 and it's already in cache, return something like "Cached: 4".

Compute and Store New Value

    cache[val] = val * 2

If val is not in the cache:

Compute val * 2.

Store it in the dictionary with val as the key.

For val = 2, it stores 2: 4.

Return Computed Result

    return f"Computed: {cache[val]}"

After storing the new value in the cache, return a string like "Computed: 4" indicating a fresh computation.

Function Calls

print(memo(2))

print(memo(2))

First call: memo(2)

2 is not in cache → computes 2 * 2 = 4, stores it → returns "Computed: 4".

Second call: memo(2)

2 is now in cache → returns "Cached: 4".

Output

Computed: 4

Cached: 4

Python Coding Challange - Question with Answer (01280525)

 

What does it do?

Outer Loop:

for i in range(1, 3):

• range(1, 3) generates numbers: 1, 2

• So, the loop runs 2 times, with i = 1 then i = 2

---

Inner Loop:

for j in range(2):

• range(2) generates numbers: 0, 1

• So, for each i, this inner loop runs twice, with j = 0, then j = 1

---

Inside Both Loops:

print(i + j)

• It prints the sum of i and j for each combination

---

 Iteration Breakdown:

i	j	i + j	Output
1	0	1	✅
1	1	2	✅
2	0	2	✅
2	1	3	✅

 Final Output:

1  
2 
2
3

---

 Summary:

• This is a nested loop.

• The outer loop controls i = 1, 2

• The inner loop controls j = 0, 1

• The program prints the sum of i + j for each combination.

Creates num_steps angles evenly spaced from 0 to

4π (two full rotations).

 5. Calculate Step Positions (x, y, z)

x = radius * np.cos(theta)

y = radius * np.sin(theta)

z = height_per_step * np.arange(num_steps)

Computes x, y coordinates on a circle of given radius (using cosine and sine).

3D Conch Shell Structure using Python

 

import numpy as np

import matplotlib.pyplot as plt

from mpl_toolkits.mplot3d import Axes3D

theta = np.linspace(0, 8 * np.pi, 500)   

z = np.linspace(0, 2, 500)               

r = z**2 + 0.1                           

phi = np.linspace(0, 2 * np.pi, 50)

theta, phi = np.meshgrid(theta, phi)

z = np.linspace(0, 2, 500)

z = np.tile(z, (50, 1))

r = z**2 + 0.1

x = r * np.cos(theta) * np.cos(phi)

y = r * np.sin(theta) * np.cos(phi)

z = r * np.sin(phi)

fig = plt.figure(figsize=(6, 6))

ax = fig.add_subplot(111, projection='3d')

ax.plot_surface(x, y, z, cmap='copper', edgecolor='none', alpha=0.9)

ax.set_title('3D Conch Shell ', fontsize=14)

ax.set_box_aspect([1,1,1])

ax.axis('off') 

plt.show()

#source code --> clcoding.com

Code Explanation:

1. Import Libraries

import numpy as np

import matplotlib.pyplot as plt

from mpl_toolkits.mplot3d import Axes3D

numpy is for numerical arrays and functions.

matplotlib is for plotting.

Axes3D is needed to enable 3D plotting in matplotlib. 

2. Define Spiral Parameters

theta_vals = np.linspace(0, 8 * np.pi, 500)  # Spiral angle: 0 to 8π

z_vals = np.linspace(0, 2, 500)              # Vertical height

phi_vals = np.linspace(0, 2 * np.pi, 50)     # Circular angle around shell's axis

theta_vals: Controls how many times the spiral wraps around — 4 full rotations.

z_vals: The height (like vertical position in the shell).

phi_vals: Describes the circle at each spiral point (the shell's cross-section). 

3. Create 2D Grids

theta, phi = np.meshgrid(theta_vals, phi_vals)

meshgrid creates a 2D grid so we can compute (x, y, z) coordinates across both theta and phi.

theta and phi will be shape (50, 500) so that we can build a surface. 

4. Define Radius and Z

z = np.linspace(0, 2, 500)

z = np.tile(z, (50, 1))       # Repeat z rows to shape (50, 500)

r = z**2 + 0.1                # Radius grows quadratically with height

z is tiled to match the (50, 500) shape of theta and phi.

r = z^2 + 0.1: Makes the radius increase faster as you go up, giving the shell its expanding spiral. 

5. Compute 3D Coordinates

x = r * np.cos(theta) * np.cos(phi)

y = r * np.sin(theta) * np.cos(phi)

z = r * np.sin(phi)

This is the parametric equation for a growing spiral swept by a circle.

theta sweeps the spiral.

phi creates a circular cross-section at each spiral point. 

The cos(phi) and sin(phi) give the circular shape.

r * cos(theta) and r * sin(theta) give the spiral path. 

6. Plotting the Shell

 fig = plt.figure(figsize=(10, 8))

ax = fig.add_subplot(111, projection='3d')

 ax.plot_surface(x, y, z, cmap='copper', edgecolor='none', alpha=0.9)

ax.set_title('3D Conch Shell Structure', fontsize=14)

ax.set_box_aspect([1,1,1])

ax.axis('off')

plt.show()

plot_surface(...): Renders a 3D surface using x, y, z.

 cmap='copper': Gives it a warm, shell-like color.

 ax.axis('off'): Hides the axis to enhance the visual aesthetics.

 set_box_aspect([1,1,1]): Keeps the plot from being stretched.

Python Coding Challange - Question with Answer (01270525)

 

Step-by-Step Explanation:

1. Initialization

n = 0

We start with n equal to 0.

---

2. while n < 4:

This loop runs as long as n is less than 4.

---

Loop Iterations:

Iteration	n before print	n == 3?	continue?	print(n)?
1	1	❌ No	❌ No	✅ Yes
2	2	❌ No	❌ No	✅ Yes
3	3	✅ Yes	✅ Yes	❌ Skipped
4	4	❌ No	❌ No	✅ Yes

What does continue do?

When n == 3, the line:

if n == 3: continue

skips the print(n) line and jumps to the next iteration of the loop.

---

 Final Output:

1  
2 
4

---

✅ Summary:

• The loop runs 4 times (as n goes from 1 to 4).

• It skips printing 3 because of the continue.

Python Coding Challange - Question with Answer (01260525)

 

Explanation:

1. range(10, 0, -2):

This creates a sequence starting from 10, going down by 2 each time, stopping before it reaches 0.

So the values of i will be:

10, 8, 6, 4, 2

2. if i < 5: break:

• The loop will stop immediately if i becomes less than 5.

• break exits the loop completely.

3. print(i):

• It only prints the value of i if the loop hasn't been broken.

---

🔁 Execution Flow:

Value of i	Condition i < 5	Action
10	False	print(10)
8	False	print(8)
6	False	print(6)
4	True	break (stop)
2	not executed	loop ended

 Final Output:

10  
8 
6

Python Coding challenge - Day 511| What is the output of the following Python Code?

 

Code Explanation:

 Line 1: Function Definition

def func(x, y=5, z=None):

func is a function with 3 parameters:

x: required argument.

y: optional, default value is 5 (not used here).

z: optional, default is None.

Line 2–3: Check and Create List if Needed

    if z is None:

        z = []

If z is None, a new empty list is created.

This ensures that a new list is created for every call, avoiding shared mutable state.

Line 4: Append to List

    z.append(x)

Adds the value of x to the list z.

Line 5: Return the List

    return z

Returns the updated list.

Function Calls and Outputs

Call 1: func(1)

z is None → creates new list [].

Appends 1 → becomes [1].

Returns [1].

Output:

[1]

Call 2: func(2)

Again, z is None → new list [].

Appends 2 → becomes [2].

Returns [2].

Output:

[2]

Final Output:

[1]

[2]

Python Coding challenge - Day 510| What is the output of the following Python Code?

 

Code Explanation:

Line 1: Function Definition

def tricky(val, s=set()):

Defines a function tricky with two parameters:

val: the value to add.

s: a set with a default argument set() (an empty set).

So s=set() is created only once and reused in all future calls unless a different s is passed.

Line 2: Add to the Set

    s.add(val)

Adds the given val to the set s.

Because s is reused, it remembers previous values added in earlier calls.

Line 3: Return the Set

    return s

Returns the modified set s.

Line 4: First Call

print(tricky(1))

tricky(1) is called.

Since no second argument is given, it uses the default set.

1 is added to the set.

The set becomes: {1}

Output: {1}

 Line 5: Second Call

print(tricky(2))

tricky(2) is called.

Uses the same default set as before (shared between calls).

Adds 2 to that set.

Now the set is: {1, 2}

Output: {1, 2}

Line 6: Third Call

print(tricky(1))

tricky(1) is called again.

Still using the same set {1, 2}.

1 is already in the set, so adding it again has no effect.

Set remains: {1, 2}

Output: {1, 2}

Final Output

{1}

{1, 2}

{1, 2}

Python Coding challenge - Day 509| What is the output of the following Python Code?

 Code Explanation:

1. Function Definition

def func(a, b=[]):

Defines a function func with two parameters:

a: required argument.

b: optional argument with a default value of an empty list [].

Important: Default parameter values are evaluated once when the function is defined, so the same list b is used across calls unless explicitly overridden.

2. Append a to List b

b.append(a)

Adds the value of a to the list b.

Since b is mutable (a list), this modifies the list in place.

3. Return the List b

return b

Returns the modified list b.

4. First Call: func(1)

print(func(1))

Calls func with a=1.

Since b is not provided, it uses the default list [].

1 is appended to the list → list becomes [1].

Returns [1].

Output: [1]

5. Second Call: func(2)

print(func(2))

Calls func with a=2.

No b provided, so it uses the same default list as before (which already contains [1]).

2 is appended → list becomes [1, 2].

Returns [1, 2].

Output: [1, 2]

6. Third Call: func(3, [])

print(func(3, []))

Calls func with a=3 and explicitly passes a new empty list [] as b.

3 is appended to this new list → [3].

Returns [3].

The default list remains unchanged as this call used a fresh list.

Output: [3]

7. Fourth Call: func(4)

print(func(4))

Calls func with a=4 and no b, so it uses the default list again.

The default list currently is [1, 2] from previous calls.

4 is appended → list becomes [1, 2, 4].

Returns [1, 2, 4].

Output: [1, 2, 4]

Final Output:

[1][1, 2][3][1, 2, 4]

Python Coding challenge - Day 507| What is the output of the following Python Code?

Code Explanation:

1. from collections import deque

Explanation:

Imports the deque class from the collections module. A deque (double-ended queue) allows fast appends and pops from both ends.

Output:

No output.

2. d = deque()

Explanation:

Creates an empty deque named d.

Current state of d:

deque([])

Output:

No output.

3. d.appendleft(1)

Explanation:

Adds 1 to the left end of the deque.

Current state of d:

deque([1])

Output:

No output.

4. d.appendleft(2)

Explanation:

Adds 2 to the left end. Since 1 is already there, 2 goes before it.

Current state of d:

deque([2, 1])

Output:

No output.

5. d.append(3)

Explanation:

Adds 3 to the right end (normal append).

Current state of d:

deque([2, 1, 3])

Output:

No output.

6. d.rotate(1)

Explanation:

Rotates the deque right by 1 position.

This means the last element moves to the front.

Before rotation:

deque([2, 1, 3])

After rotation:

deque([3, 2, 1])

7. print(list(d))

Explanation:

Converts the deque to a list and prints it.

Output:

[3, 2, 1]

Python Coding challenge - Day 506| What is the output of the following Python Code?

Code Explanation:

1. from collections import deque

Purpose: Imports the deque class from Python’s collections module.

Effect: Enables usage of deque, a double-ended queue optimized for fast appends and pops from both ends.

2. d = deque([11, 12, 13, 14, 15])

Purpose: Creates a deque object d initialized with the list [11, 12, 13, 14, 15].

Effect: d is now a double-ended queue containing these elements in order.

3. d.rotate(2)

Purpose: Rotates the deque d 2 steps to the right.

Effect: The last two elements move to the front:

Before rotation: [11, 12, 13, 14, 15]

After rotation: [14, 15, 11, 12, 13]

4. print(list(d))

Purpose: Converts the deque d back into a regular list and prints it.

Effect: Outputs [14, 15, 11, 12, 13] to the console.

Final output:

[14, 15, 11, 12, 13]
