I want to print something only once in a while loop and if I change the string while running the file it would work in python

Question

Code:

while True:
 text = 'fizz'
 if text == 'fizz':
  print('fizz')
 elif text == 'buzz':
  print('buzz')

I want to print fizz once if text = 'fizz' and if I replace text = 'fizz' with text = 'buzz' while the file is running it still prints buzz.

Is this possible and how to do it if it is?
