Python Coding challenge - Day 1160| What is the output of the following Python Code?

 

Code Explanation:

🔹 1. Creating an Empty List

context = []

✅ Explanation:

An empty list named context is created.

Current state:

[]

🔹 2. Starting the Loop

for i in range(3):

✅ Explanation:

range(3) generates:

0, 1, 2

Loop will run 3 times.

🔹 3. First Iteration

Value of i

i = 0

Executing

context.append(i)

List becomes

[0]

🔹 4. Second Iteration

Value of i

i = 1

Executing

context.append(i)

List becomes

[0, 1]

🔹 5. Third Iteration

Value of i

i = 2

Executing

context.append(i)

List becomes

[0, 1, 2]

🔹 6. Loop Ends

After all iterations:

context

contains:

[0, 1, 2]

🔹 7. Removing First Element

context.pop(0)

✅ Explanation:

pop(index) removes and returns the element at that index.

Here index is:

0

which is the first element.

Removed value:

0

List becomes:

[1, 2]

🔹 8. Printing the List

print(context)

✅ Explanation:

Prints the final contents of the list.

🎯 Final Output
