Python Coding challenge - Day 644| What is the output of the following Python Code?

 

Code Explanation:

1. Function Definition: make_funcs()

def make_funcs():

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

This function returns a list of 3 lambda functions.

Each lambda is defined as: lambda x: i * x

The loop for i in range(3) goes through i = 0, 1, 2

BUT: i is captured by reference, not value — this is called late binding.

2. Calling make_funcs()

funcs = make_funcs()

Now funcs is a list of three lambda functions, but all of them refer to the same i, which ends up being 2 after the loop finishes.

3. Evaluating the Lambdas

results = [f(2) for f in funcs]

Each f(2) now evaluates i * 2, but since i = 2 at the end of the loop:

f(2) = 2 * 2 = 4

All lambdas return 4

So results = [4, 4, 4]

4. Final Output

print(results)

Output:

[4, 4, 4]
