Python Coding Challenge - Question with Answer (ID -170526)

 

Explanation:

Step 1: range(2)

What it does

range(2)

creates numbers:

0, 1

So loop will run 2 times.

Step 2: Start of for Loop

Line

for i in range(2):

Meaning

Variable i stores values one by one

First i = 0

Then i = 1

Step 3: First Iteration

Current value

i = 0

Executed line

pass

Meaning

pass means:

Do nothing

So nothing happens.

Step 4: Second Iteration

Current value

i = 1

Executed line

pass

Again, nothing happens.

Step 5: Loop Ends

The loop finishes normally because:

all values are completed

no break statement is used

So Python goes to the else block.

Step 6: else Block Executes

Line

else:

    print(i)

Current value of i

1

because last loop iteration stored 1 in i.

Step 7: Output

Printed value

1

Final Output

1
