End Loop

The loop checks conditions each iteration. 'break' stops the loop immediately. 'continue' skips the rest of the current iteration and moves to the next.

Execution Sample

Python

for i in range(5):
    if i == 3:
        break
    if i == 1:
        continue
    print(i)

Loop from 0 to 4, breaks at 3, skips printing at 1, prints other numbers.

Execution Table

Iteration	i	Condition i==3?	Action	Output
1	0	False	Print 0	0
2	1	False	Continue (skip print)
3	2	False	Print 2	2
4	3	True	Break loop
-	-	-	Loop ends	-

💡 Loop ends because i == 3 triggers break

Key Moments - 3 Insights

Why does the loop stop completely when i equals 3?

Because the 'break' statement runs at i == 3 (see execution_table row 4), it immediately exits the loop, stopping all further iterations.

Why is there no output when i equals 1?

At i == 1 (execution_table row 2), the 'continue' statement skips the print step, so nothing is printed for that iteration.

Does 'continue' stop the whole loop?

No, 'continue' only skips the rest of the current loop iteration and moves to the next one, unlike 'break' which stops the loop entirely.

Visual Quiz - 3 Questions

Look at the execution table, what is the value of i when the loop breaks?

A 1

B 2

C 3

D 0

💡 Hint

Check the row where 'Action' is 'Break loop' in the execution_table.

At which iteration does the 'continue' statement cause the loop to skip printing?

A Iteration 1

B Iteration 2

C Iteration 3

D Iteration 4

💡 Hint

Look at the execution_table row where 'Action' is 'Continue (skip print)'.

If the 'break' statement was removed, what would be the last value printed?

A 4

B 3

C 2

D 1

💡 Hint

Without break, the loop runs through all i in range(5), so last printed is the last i not skipped.

Concept Snapshot

for i in range(n):
    if break_condition:
        break  # stops loop entirely
    if continue_condition:
        continue  # skips to next iteration
    # rest of loop body

'break' exits loop immediately.
'continue' skips current iteration only.

Full Transcript

This visual execution shows how 'break' and 'continue' work inside a Python loop. The loop runs from 0 to 4. When i equals 3, the 'break' stops the loop completely, so no more numbers print after that. When i equals 1, the 'continue' skips printing just for that iteration, but the loop keeps going. The variable i changes each iteration, and the actions depend on conditions. This helps understand how these two statements control loop flow differently.
