Python Coding challenge - Day 1097| What is the output of the following Python Code?

 

Code Explanation:

1️⃣ Creating an Empty List

funcs = []

Explanation

An empty list named funcs is created.

This list will store function objects.

2️⃣ Starting the Loop

for i in range(3):

Explanation

Loop runs 3 times.

Values of i:

0, 1, 2

3️⃣ Defining the Function Inside Loop

def f():

    return i

Explanation

A function f is defined inside the loop.

It returns the variable i.

⚠️ Important:

The function does not store the value of i at creation time.

It stores a reference to the variable i.

4️⃣ Appending Function to List

funcs.append(f)

Explanation

The function f is added to the list.

This happens 3 times, so funcs contains 3 functions.

👉 But all functions refer to the same variable i.

5️⃣ Loop Ends

After loop finishes, the value of i becomes:

2

6️⃣ Calling Each Function

for fn in funcs:

    print(fn())

Explanation

Each stored function is called.

When called, each function returns the current value of i.

👉 Since i = 2 after loop ends:

📤 Final Output

2

2
