How do I break from a while and for loop?

Question

I am trying to break from a while and for loop as below whenever retry and last_submitted_tag_retryare equal but it doesn't, how do I break from this loop?

import re
retry = 0
last_submitted_tag_retry = 0 
train = 'train1'

output = '''Thu Jan 24 18:08:18 2019 firstname lastname <first_last@company.com> submitted project-394 to train1
