🚀 Day 43/150 – Power of a Number in Python

Finding the power of a number means raising a number to an exponent.

Example:
2³ = 2 × 2 × 2 = 8
5² = 25

Let’s explore different ways to calculate power in Python 👇

---

🔹 Method 1 – Using ** Operator

base = 2
exp = 3

result = base ** exp

print("Power:", result)






✅ Easiest and most common method.

---

🔹 Method 2 – Using pow() Function

base = 2
exp = 3

result = pow(base, exp)

print("Power:", result)






✅ Built-in function for power calculation.

---

🔹 Method 3 – Using Loop

base = 2
exp = 3
result = 1

for i in range(exp):
    result *= base

print("Power:", result)

✅ Good for understanding logic.

---

🔹 Method 4 – Taking User Input

base = int(input("Enter base: "))
exp = int(input("Enter exponent: "))

print("Power:", base ** exp)

✅ Dynamic version.

---

🔹 Method 5 – Using Recursion

def power(base, exp):
    if exp == 0:
        return 1
    return base * power(base, exp - 1)

print(power(2, 3))

✅ Great for learning recursion.

---

🔹 Output

Power: 8

Python Coding Challenge - Question with Answer (ID -090526)

 

Explanation:

🔹 Step 1: Create Tuple

x = ([],)

x is a tuple

Tuple is immutable ❗

Inside tuple:

[]

is a mutable list

👉 Current value:

([],)

🔹 Step 2: Execute x[0] += [1]

x[0] += [1]

This line is tricky 😈

Python internally performs TWO actions.

⚡ Step 2.1: Modify the List

[] += [1]

This updates list in-place.

👉 List becomes:

[1]

So internally:

x → ([1],)

⚡ Step 2.2: Try Reassignment

After modifying list, Python also tries:

x[0] = [1]

⚠️ But tuple is immutable ❌

Tuple does NOT allow item assignment.

🔹 Step 3: Error Occurs

Python raises:

TypeError

👉 Program stops here

🔹 Step 4: print(x) Never Executes

print(x)

This line is never reached because error already happened.

⚡ Important Twist 😈

Even though error occurs:

👉 list WAS modified before error

Internally tuple becomes:

([1],)

But print never runs.

🔥 Final Output

TypeError

🚀 Day 42/150 – ASCII Value of a Character in Python

The ASCII value is the numeric code assigned to characters.

Example:
A = 65
a = 97
0 = 48

Let’s explore different ways to find ASCII value in Python 👇

🔹 Method 1 – Using ord()

ch = 'A' print("ASCII Value:", ord(ch))

✅ ord() returns the ASCII/Unicode value.

🔹 Method 2 – Taking User Input
ch = input("Enter a character: ")

print("ASCII Value:", ord(ch))


✅ Dynamic version.

🔹 Method 3 – Using Function
def get_ascii(ch):
    return ord(ch)

print(get_ascii('a'))



✅ Reusable approach.

🔹 Method 4 – Using Loop for String
text = "ABC"

for ch in text:
    print(ch, "=", ord(ch))



✅ Useful for multiple characters.

🔹 Method 5 – Using Dictionary Comprehension
chars = ['A', 'B', 'C']

ascii_values = {ch: ord(ch) for ch in chars}

print(ascii_values)



✅ Great for storing multiple values.
🔹 Output
ASCII Value: 65


🔥 Key Takeaways
✔️ Use ord() to get ASCII value

✔️ Works for letters, digits, symbols

✔️ Useful in encoding problems

✔️ Can handle single or multiple characters

Python Coding Challenge - Question with Answer (ID -080526)

 

Explanation:

🔹 Step 1: Create Generator

x = (i for i in range(4))

This creates a generator object

Values inside generator:

0, 1, 2, 3

⚠️ Important:

Generator values are produced one by one

Once used → they disappear 😈

🔹 Step 2: Execute sum(x)

sum(x)

Python starts consuming generator:

0 + 1 + 2 + 3 = 6

👉 Result:

6

🔹 Step 3: Generator Gets Exhausted

After sum(x):

x → empty generator

⚠️ All values already consumed

Generator now has:

nothing left

🔹 Step 4: Execute list(x)

list(x)

But generator already empty ❗

So:

[]

🔹 Step 5: Print Final Output

print(6, [])

👉 Final Output:

6 []

Python Coding challenge - Day 1146| What is the output of the following Python Code?

 

 Code Explanation:

🔹 1. Outer Function Definition

def outer(x):

✅ Explanation:

A function outer is defined.

It takes one argument: x.

This function will return another function.

🔹 2. Inner Function Definition

def inner(y):

✅ Explanation:

Inside outer, another function inner is defined.

It takes parameter y.

🔹 3. Using Outer Variable Inside Inner

return x + y

✅ Explanation:

inner uses:

y → its own parameter

x → from outer function

👉 This is called a closure:

Inner function remembers the value of x even after outer finishes

🔹 4. Returning Inner Function

return inner

✅ Explanation:

outer does NOT return a value directly

It returns the function inner itself

🔹 5. Calling Outer Function

f = outer(5)

🔍 What happens:

outer(5) is executed

x = 5

Returns inner function

👉 Now:

f → inner (with x = 5 stored)

🔹 6. Calling Returned Function

print(f(3))

🔍 What happens:

Calls:

inner(3)

Inside inner:

x = 5 (remembered from closure)

y = 3

Calculation:

5 + 3 = 8

🎯 Final Output

8

Python Coding Challenge - Question with Answer (ID -060526)

 

Explanation:

🔹 Step 1: Create Generator

x = (i for i in range(4))

This creates a generator object

Values generated:

0, 1, 2, 3

⚠️ Important:

Generator values are used only once

After consuming values → generator becomes empty 😈

🔹 Step 2: Execute sum(x)

sum(x)

Python starts consuming generator values:

0 + 1 + 2 + 3 = 6

👉 Result:

6

⚠️ Now generator x is exhausted:

x → empty

🔹 Step 3: Execute max(x, default=0)

max(x, default=0)

But generator already consumed all values ❗

So internally:

max([], default=0)

👉 Since generator is empty:

default=0 is returned

👉 Result:

0

🔹 Step 4: Print Final Output

print(6, 0)

👉 Output:

6 0

Example:
LCM of 4 and 6 = 12

Let’s explore different ways to find LCM in Python 👇

🔹 Method 1 – Using Loop

a = 4 b = 6 greater = max(a, b) while True: if greater % a == 0 and greater % b == 0: print("LCM:", greater) break greater += 1

✅ Starts from the greater number and checks multiples.

🔹 Method 2 – Taking User Input
a = int(input("Enter first number: "))
b = int(input("Enter second number: "))

greater = max(a, b)

while True:
    if greater % a == 0 and greater % b == 0:
        print("LCM:", greater)
        break
    greater += 1





✅ Dynamic version using user input.
🔹 Method 3 – Using GCD Formula
Formula:
LCM = (a × b) // GCD(a, b)
import math

a = 4
b = 6

lcm = (a * b) // math.gcd(a, b)

print("LCM:", lcm)




✅ Fastest and most efficient method.
🔹 Method 4 – Using Function
import math

def find_lcm(a, b):
    return (a * b) // math.gcd(a, b)

print(find_lcm(4, 6))




✅ Reusable and clean code.

Python Coding challenge - Day 1143| What is the output of the following Python Code?

 

Code Explanation:

🔹 1. Class Definition

class Test:

✅ Explanation:

A class Test is created.

It will store a list in each object.

🔹 2. Constructor (__init__)

def __init__(self, x=[]):

    self.x = x

✅ Explanation:

Constructor runs when object is created.

Parameter x=[] is a default argument.

⚠️ Important:

This list is created only once

It is shared across all objects

🔹 3. Assigning to Instance

self.x = x

✅ Explanation:

Assigns the same list (x) to the object

Since x is shared → all objects refer to same list

🔹 4. Creating First Object

a = Test()

✅ What happens:

No argument passed → uses default list []

So:

a.x → []

🔹 5. Creating Second Object

b = Test()

✅ What happens:

Again uses SAME default list

So:

b.x → []

⚠️ Key Insight:

a.x is b.x → True

👉 Both refer to same list

🔹 6. Modifying List via a

a.x.append(1)

✅ Explanation:

Adds 1 to the shared list

So now:

a.x → [1]

b.x → [1]

🔹 7. Printing b.x

print(b.x)

✅ Output:

[1]

Final Output:

[1]

Python Coding challenge - Day 1142| What is the output of the following Python Code?

 

Code Explanation:

🔹 1. Function Definition

def func(x, lst=[]):

✅ Explanation:

A function func is defined with:

x → number of iterations

lst=[] → default list

⚠️ Important:

This list is created only once (when function is defined, not called)

It is shared across all function calls

🔹 2. Loop Execution

for i in range(x):

✅ Explanation:

Loop runs from 0 to x-1

Adds numbers step by step

🔹 3. Appending Values

lst.append(i)

✅ Explanation:

Adds i into the same list lst

Since lst is shared → values accumulate over calls

🔹 4. Returning List

return lst

✅ Explanation:

Returns the updated list

🔹 5. First Function Call

print(func(3))

🔍 Execution:

x = 3

Loop runs: 0,1,2

List becomes:

[0, 1, 2]

✔️ Output:

[0, 1, 2]

🔹 6. Second Function Call

print(func(2))

🚨 Important:

Python does NOT create a new list

It uses the SAME previous list → [0,1,2]

🔍 Execution:

x = 2

Loop runs: 0,1

These values are appended to existing list:

[0,1,2] + [0,1] → [0,1,2,0,1]

✔️ Output:

[0, 1, 2, 0, 1]

🎯 Final Output

[0, 1, 2]

[0, 1, 2, 0, 1]
