why do we use while loop in python code example

Example 1: python do while

# Python does not have a do-while loop. You can however simulate
# it by using a while loop over True and breaking when a certain
# condition is met.
# Example:
i = 1
while True:
    print(i)
    i = i + 1
    if(i > 3):
        break

Example 2: while loop in python

# while loop runs till the condition becomes false
number = 0
while number > 10:		# prints number till 10
  print(number)
  number += 1
