while loop

2

while some_condition:

a block of statements

while loop

3

i = 1

while i <= 10:

print(i ** 2)

i += 1

while loop

4

n = int(input())

length = 0

while n > 0:

n //= 10 length += 1 print(length)

while loop with else

5

i = 1

while i <= 10:

print(i)

i += 1 else:

print('Loop ended, i =', i)

while loop with else - break

6

total_sum = 0

a = int(input())

while a != 0:

total_sum += a

if total_sum >= 21:

print('Total sum is', total_sum) break

a = int(input())

else:

print('Total sum is < 21 and is equal to', total_sum, '.')

for loop with else

7

for i in range(5):

a = int(input())

if a < 0:

print('Met a negative number', a) break

else:

print('No negative numbers met')

continue in loops

8

for num in range(2, 10):

if num % 2 == 0:

print("Found an even number", num) continue

print("Found a number", num)

break & continue with nested loop

9

for i in range(3):

for j in range(5):

if j > i:

# breaks only the inner for break

print(i, j)

1 line while loop

10

i = 1

while (i<10): print (i); i += 1
