Loops in Python

A for loop is useful when we want to repeat something a fixed number of times or go through items in a sequence.

for i in range(5):
    print(i)

Output

0
1
2
3
4

While Loop

A while loop runs as long as its condition is true.

i = 1

while i <= 5:
    print(i)
    i += 1

Output

1
2
3
4
5

Break and Continue

Sometimes we need to control how a loop works.

Break

break is used to stop the loop completely.

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

Continue

continue skips the current iteration and moves to the next one.

for i in range(5):
    if i == 2:
        continue
    print(i)
