Day 19 - Break and Continue

In loop sometimes we want to break out of the loop or skip some iteration depening upon some condition and continue with next iteration

Break

When is used when we want to end the loop depending upon some condition(in programming terms breaking out of the loop). Number of iterations left are matter of least concern.

Example:

for i in range(10):
    print(i)
    if(i==5):
        print('Not gonna cross 5')
        break

Output:

0
1
2
3
4
5
Not gonna cross 5

Continue

When we want to skip an iteration not the entire loop then we use continue.

Example:

for i in range(1, 21):
    if(i%2==0):
        continue
    print(i)

Output:

1
3
5
7
9
11
13
15
17
19

Emulating do while loop: Solution to previous lecture question

i=0
while True:
    print(i)
    i=i+1
    if(i%100==0):
        break
