Python Coding challenge - Day 570| What is the output of the following Python Code?

 

Code Explanation:

1. Function outer() is called

funcs = []

An empty list is created to hold functions.

for i in range(3):

    funcs.append(lambda: i)

Loop runs i = 0, 1, 2

In each iteration, it appends a lambda function that returns i.

BUT — this is the key point:

Lambdas do not capture the current value of i at the time they're created.

Instead, they capture the variable itself, not its value.

So after the loop finishes, i = 2, and all three lambdas refer to the same variable i, which now equals 2.

2. Returned Functions

f1, f2, f3 = outer()

The list of 3 lambda functions is returned.

All 3 functions are effectively: lambda: i, where i = 2 (final value after the loop)

3. Print the Results

print(f1(), f2(), f3())

Each function returns i, and since i = 2, the output is:

2 2 2

Final Output:

2 2 2
