While Loop Statements

Looping statements are used to execute the same instruction again and again until the conditions get satisfied

While Loop

While loop not require any iterable, it will execute a block of code repeatedly until the condition get fails

#While Loop
count = 0

#Looping for 5 times
while count<5:
    print(count)
    #Increment is mandatory here, otherwise results in infinite loop
    count=count+1

Output

While Break

Even though the condition is true still we can stop the loop with the help of break statement

#While Break Loop
count = 0

#Looping for 3 times
while count<5:
    print(count)
    count=count+1
    #break the loop when count is 3
    if count==3:
        break

Output

0
1
2

While Continue

Even though the condition is true still we can stop the specific iteration using continue statement

#While Continue
count = 0

#Looping for 4 times
while count<5:
    count=count+1
    #skip the print when count is 3
    if count==3:
        continue
    print(count)

Output

While Else

One of the unique feature in python is while loop with else clause

#While Else
count = 0

#Looping for 4 times
while count<5:
    count=count+1
    print(count)
else:
    print("Loop broken - count is higher than 5 now")

Output

1
2
3
4
5
Loop broken - count is higher than 5 now

While Break Else

One of the unique feature in python is while loop with else clause

#While Break Else
count = 0

#Looping for 4 times
while count<5:
    count=count+1
    if count==3:
        break
    print(count)
#Else statement won't execute since loop breaks
else:
    print("Loop broken - count is higher than 5 now")

Output

1
2

While Continue Else

Else statement execute for continue since it will only skip only the particular execution

#While Continue Else
count = 0

while count<5:
    count=count+1
    if count==3:
        continue
    print(count)
#Else statement execute since loop continues
else:
    print("Loop broken - count is higher than 5 now")

Output

1
2
4
5
Loop broken - count is higher than 5 now
