What are While loops in Python?

With the while loop, we can execute a set of statements as long as a condition is true.

Syntax

while condition:
    return statement
    increment/decrement

The while loop requires relevant variables to be ready, in this example, we need to define an indexing variable, i, which we set to 1.

Example:

Print i as long as i is less than 6

i = 1
while i < 8:
    print(i)
    i += 1 
#1
#2
#3
#4
#5
#6
#7

Break Statement

The Break Statement can help to stop the loop even if the condition is true

Syntax

while condition:
    return statement
    if condition:
        break
    increment/decrement

Example

i = 1
while i < 8:
    print(i)
    if i == 3:
        break
    i += 1

#1
#2
#3

Continue Statement

Unlike the break statement, the continue statement will stop only the current iteration and continues with the next iteration.

Syntax

while condition:
    return statement
    if condition:
        continue
    increment/decrement

Example

i = 0
while i < 8:
    i += 1
    if i == 3:
        continue
    print(i)
#1
#2
#4
#5
#6
#7
#8
