when would you usea while loop 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: python while

# a while loop repeats its instructions as long as the condition is met
# this one will loop indefinitely
python_is_cool = True

while python_is_cool:
  print("I love python!")
  
# while loops are useful when you don't know the number 
# of times you want to iterate in advance
