Python - For Loop

What happens when you use a nested for loop in Python?

AThe outer loop runs only once

BThe inner loop runs completely for each iteration of the outer loop

CBoth loops run at the same time

DThe loops run only if they have the same range

Step-by-Step Solution

Solution:

Step 1: Understand nested loops structure
The outer loop starts and for each iteration, the inner loop runs fully.
Step 2: Observe loop execution order
For every single step of the outer loop, the inner loop completes all its steps before the outer loop moves on.
Final Answer:
The inner loop runs completely for each iteration of the outer loop -> Option B
Quick Check:
Nested loop execution = inner loop runs fully each outer loop step [OK]

Quick Trick: Inner loop runs fully inside each outer loop step [OK]
