3. While True loops

See: https://www.w3schools.com/python/python_while_loops.asp

While loops run a set of statements as long as a test condition is true.

3.1. While true

while True: loops run forever.

Instead of using a condition that returns True or False, True is used in place of the condition to make the condition always True. As a result, the while loop runs forever.

The statements within the loop are indented with the tab key (which is equivalent to 4 spaces) to make those lines part of the while loop.

The while True loop below prints the text I never stop, over and over again.

while True:
    print('I never stop')
