Python Coding challenge - Day 567| What is the output of the following Python Code?

 


Code Explanation:

1. Function Definition: counter()
def counter():
    x = [0]
A function named counter is defined.
Inside it, a list x with a single element 0 is created.
The list is used instead of an integer because lists are mutable, which allows the inner function to modify the value.

2. Inner Function: inc()
    def inc():
        x[0] += 1
        return x[0]
inc() is a nested function (also called a closure).
It accesses the variable x from the outer scope (nonlocal variable).
x[0] += 1 increments the first element of the list.
It then returns the incremented value.

3. Returning the Closure
    return inc
The counter() function returns the inner function inc, not its result.
This means calling counter() gives you a new counter function that you can call repeatedly.

4. Using the Counter
c = counter()
c now holds the inc function.
But it remembers the x = [0] from when counter() was first called — this is what makes it a closure.

5. Calling the Counter Twice
print(c(), c())
First call: c() → x[0] becomes 1, returns 1
Second call: c() → x[0] becomes 2, returns 2
So, the output is:
1 2

Final Output
1 2

Python Coding challenge - Day 566| What is the output of the following Python Code?

 


Code Explanation:

1. Importing reduce Function
from functools import reduce
The reduce() function is part of the functools module in Python.
reduce() applies a function cumulatively to the items of an iterable (like a list), from left to right, reducing the iterable to a single value.
Example: reduce(lambda x, y: x + y, [1, 2, 3]) results in ((1 + 2) + 3) = 6.

2. Defining the List
nums = [1, 2, 3, 4]
This creates a list named nums containing four integers: [1, 2, 3, 4].

3. Applying reduce with a Lambda Function
res = reduce(lambda acc, x: acc - x, nums)
reduce() will use the lambda function to combine all elements of nums one by one.
The lambda function: lambda acc, x: acc - x takes two arguments:
acc is the accumulated result so far
x is the current item in the list

Step-by-step Breakdown:
Starting with the first two elements:
Step 1: acc = 1, x = 2 → 1 - 2 = -1
Step 2: acc = -1, x = 3 → -1 - 3 = -4
Step 3: acc = -4, x = 4 → -4 - 4 = -8
Final result: res = -8

4. Printing the Result
print(res)
This outputs the final reduced result to the console:

Final Output
-8

Python Coding Challange - Question with Answer (01230625)

 


Step-by-step Explanation:

  1. Original list:


    x = [1, 2, 3]
  2. What is x[::-1]?

    • This is list slicing with a step of -1.

    • It means reverse the list.

    • So x[::-1] becomes:


      [3, 2, 1]
  3. Comparison:


    x == x[::-1]
    • Now you are comparing:


      [1, 2, 3] == [3, 2, 1]
  4. Result:

    • The two lists are not equal, so:


      print(False)

 Final Output:


False

 Summary:

  • [::-1] reverses a list.

  • The original list and its reversed version are not equal here, so the output is False.

Python Coding challenge - Day 564| What is the output of the following Python Code?

 


Code Explanation:

1. Defining the compose Function
def compose(f, g):
    return lambda x: f(g(x))
Explanation:
This defines a function called compose which takes two functions f and g as arguments.
It returns a new function (using a lambda expression) that:
Takes an input x
First applies g to x → g(x)
Then applies f to the result → f(g(x))
This is function composition, where the output of g becomes the input to f.

2. Defining Function f
f = lambda x: x + 1
Explanation:
f is defined as a lambda function (anonymous function).
It takes input x and returns x + 1.
Example:
If x = 3, then f(3) returns 4.

3. Defining Function g
g = lambda x: x * 2
Explanation:
g is another lambda function.
It takes input x and returns x * 2.
Example:
If x = 3, then g(3) returns 6.

4. Creating the Composed Function h
h = compose(f, g)
Explanation:
We call the compose function with f and g as inputs.
h now becomes a new function defined as:
h(x) = f(g(x))
So for any input x, h(x) will first double x (via g), then add 1 (via f).

5. Printing the Result of h(3)
print(h(3))
Explanation:
This calls the composed function h with input 3.
It computes:
g(3) = 3 * 2 = 6
f(6) = 6 + 1 = 7
So, h(3) returns 7.

Output:
7

Python Coding challenge - Day 565| What is the output of the following Python Code?

 


Code Explanation:

1. Defining the factory Function
def factory(n):
    return lambda x: x ** n
Explanation:
factory is a function that takes a parameter n.
It returns a lambda function that takes x and returns x ** n (i.e., x raised to the power n).
This is a function factory – it generates power functions dynamically.
Example:
factory(2) will return a function that squares its input (x ** 2)
factory(3) will return a function that cubes its input (x ** 3)

2. Creating the square Function
square = factory(2)
Explanation:
Calls factory(2), which returns lambda x: x ** 2
So square is now a function that returns the square of any input.
Example:
square(3) → 3 ** 2 = 9

3. Creating the cube Function
cube = factory(3)
Explanation:
Calls factory(3), which returns lambda x: x ** 3
So cube is now a function that returns the cube of any input.
Example:
cube(2) → 2 ** 3 = 8

4. Printing the Results
print(square(3), cube(2))
Explanation:
square(3) → 3 ** 2 = 9
cube(2) → 2 ** 3 = 8

Output:
9 8

Python Coding Challange - Question with Answer (01220625)

 


 Explanation:

  • x is a string:


    x = "clcoding"
  • When you multiply a string by an integer:


    x * 0

    It repeats the string 0 times, which means no characters are printed.


✅ Output:

# Blank output (empty string)

 Summary:

In Python:

  • "abc" * 3 → "abcabcabc"

  • "abc" * 0 → "" (empty string)

So, print(x * 0) prints nothing, but it doesn't cause an error.

Python Coding challenge - Day 563| What is the output of the following Python Code?

 


Code Explanation:

1. Defining the Outer Function: base(x)
def base(x):
This defines a function called base that takes one argument x.
This function will return another function inside it.

2. Defining the Inner Function: powr(y)
    def powr(y):
        return x ** y
Inside base, a new function powr is defined.
powr takes one argument y.
It returns x ** y, which is x raised to the power of y.
Important: x is captured from the outer function (base) — this is called a closure.

3. Returning the Inner Function
    return powr
Instead of returning a value directly, base returns the inner function powr.
This means calling base(x) gives you a custom power function that always uses x as the base.

4. Using the Function: calc = base(2)
calc = base(2)
This calls base(2), which means:
x = 2
A new function powr(y) is created, where x = 2 is stored.
calc now holds that inner function:
calc(y) → 2 ** y

5. Calculating calc(5)
print(calc(5))
calc(5) calls the powr function where x = 2 (from earlier), and y = 5.
So it calculates:
2 ** 5 = 32

Final Output
32

Python Coding challenge - Day 562| What is the output of the following Python Code?

 



Code Explanation:

1. Function Definition: merge(f, g)
def merge(f, g):
    return lambda x: f(x) - g(x)
This defines a function merge that takes two functions as input: f and g.
It returns a new function (a lambda) that takes one argument x.
This lambda computes:
f(x) - g(x)
i.e., it applies both functions to x, and subtracts the result of g(x) from f(x).

2. Defining Function f
f = lambda x: x * 3
This defines f as a lambda function that takes a number x and returns x * 3.
For example:
f(2) → 2 * 3 → 6

3. Defining Function g
g = lambda x: x + 4
This defines g as a lambda function that takes a number x and returns x + 4.
For example:
g(2) → 2 + 4 → 6

4. Creating a New Function h Using merge
h = merge(f, g)
This calls the merge function with f and g.
merge(f, g) returns a new function that computes: f(x) - g(x)
So, h(x) now means: f(x) - g(x) → x*3 - (x+4)

5. Evaluating h(2)
print(h(2))
Let's compute step by step:
f(2) → 2 * 3 → 6
g(2) → 2 + 4 → 6
So, h(2) = f(2) - g(2) = 6 - 6 = 0
Therefore, the result printed is:
0

Final Output
0

The Walrus Operator (:=) in Python Explained!

Introduced in Python 3.8, the walrus operator (:=) has made code more concise and readable by allowing assignment inside expressions. It’s officially known as the assignment expression operator.

But why the name walrus?
Because the operator := looks like the eyes and tusks of a walrus.

The walrus operator lets you assign a value to a variable as part of an expression — usually inside a while, if, or list comprehension.

variable := expression

This assigns the result of expression to variable and returns it — allowing use within the same line.

text = input("Enter text: ")
while text != "exit":
    print("You typed:", text)
    text = input("Enter text: ")
while (text := input("Enter text: ")) != "exit":
    print("You typed:", text)

Cleaner, more readable, fewer lines.

while (line := input(">> ")) != "quit":
    print("Echo:", line)
nums = [1, 5, 10, 15, 20]
result = [n for n in nums if (half := n / 2) > 5]
print(result)  # [10, 15, 20]
data = "Hello World"
if (length := len(data)) > 5:
    print(f"String is long ({length} characters)")
  • Don’t overuse it in complex expressions — it may reduce readability.
  • Use only when assignment and usage naturally go together.
Feature Walrus Operator
Introduced In Python 3.8
Syntax x := expression
Nickname Walrus Operator
Benefit Assign + use in a single expression
Common Use Cases Loops, conditionals, comprehensions

The walrus operator is a powerful addition to Python — especially when writing clean, efficient code. Like any tool, use it where it makes your code clearer — not just shorter.

Happy coding!

Python Coding Challange - Question with Answer (01210625)

 


Step-by-Step Execution:

  1. Function Definition

    def gen():
    yield 10
    • This defines a generator function.

    • The keyword yield makes gen() return a generator object, not a regular value.

  2. Create Generator


    g = gen()
    • Now, g is a generator object that will produce values when next(g) is called.

  3. First next(g)

    next(g)
    • This starts the generator.

    • It runs the function up to the first yield, which is:

      yield 10
    • So it yields 10, and pauses.

  4. Second next(g)


    next(g)
    • The generator resumes after the yield.

    • But there's nothing left in the function.

    • So it raises a StopIteration exception.


 What Happens When You Run It?

  • First next(g) → works, returns 10.

  • Second next(g) → raises:

    StopIteration

✅ Visual Summary:


def gen():
yield 10 ← (1st call yields 10) ↑ paused here -- 2nd next(g) resumes here
-- But function is over ⇒ StopIteration

✅ Final Advice:

If you want to handle it safely:


g = gen()
print(next(g)) try: print(next(g)) except StopIteration:
print("Generator exhausted")
