Python Coding challenge - Day 494| What is the output of the following Python Code?

 Code Explanation:

1. Function Definition

def get_funcs():

    return [lambda x=i: x*2 for i in range(3)]

What it does:

Defines a function get_funcs() that returns a list of lambda functions.

The list comprehension [lambda x=i: x*2 for i in range(3)] creates 3 lambdas:

Each lambda captures the current value of i using x=i as a default argument.

Each lambda, when called without arguments, will return x * 2.

What's inside the returned list:

Equivalent to:

[

  lambda x=0: x*2,

  lambda x=1: x*2,

  lambda x=2: x*2

]

Each lambda will return:

0 * 2 = 0

1 * 2 = 2

2 * 2 = 4

 2. Calling the Lambdas

results = [f() for f in get_funcs()]

What it does:

Calls each lambda function returned by get_funcs().

Each function f() uses its default argument x=i, and returns x*2.

Step-by-step:

f = lambda x=0: x*2 → f() → returns 0

f = lambda x=1: x*2 → f() → returns 2

f = lambda x=2: x*2 → f() → returns 4

Resulting list:

results = [0, 2, 4]

3. Print the Results

print(results)

Output:

[0, 2, 4]
