Check out these examples to get a clear idea of how while loops work in Python. Let’s dive right in. 1. Example of using while loops in Python. n = 1 while n < 5: print ("Hello Pythonista") n = n+1. 2. Example of using the break statement in while loops. In Python, we can use the break statement to end a while loop prematurely.
Python while Loop. In Python, we use a while loop to repeat a block of code until a certain condition is met. For example, number = 1 while number <= 3: print (number) number = number + 1. Output. 1 2 3. In the above example, we have used a while loop to print the numbers from 1 to 3.
