Learn Python like a Professional! Take You from 0 to Hero

In this Python lecture, we will learn about the while loop, break, continue.

"while loop in Python is used to iterate over a block of code as long as the condition is true".

Let's see some example-

Create while loop

#  Display print the 'Hello' 3-times

count=0
while count < 3 :
    print('Hello')
    count += 1

>> Hello
Hello
Hello

# Display and increment the value of variable on each iteration by 1

x=0
while x < 5 :
    print('current value of x=',x)
    x += 1

>> current value of x= 0
  current value of x= 1
  current value of x= 2
  current value of x= 3
  current value of x= 4

Break & continue

# break statement is used to terminate the loop

x=0
while x < 5 : 
    print('current value of x=',x) 
    if x==2:
        print('\nAlert!! x is equal to 2')
        break
    x += 1

>> current value of x= 0
current value of x= 1
current value of x= 2

Alert!! x is equal to 2

# #Continue forces the next iteration of the loop to take place, skipping any code in between.

x=0
while x < 5 :

    x += 1

    if x==2:
        continue

    print('current value of x=',x)

>>  current value of x= 1
  current value of x= 3
  current value of x= 4
  current value of x= 5
