what does "while True" really mean?

I see Kenneth has used twice "while True" for the big loop. What does "while True" mean? What is considered "False"? Is there an alternative for this?

True is a boolean value. A while loop will evaluates the given condition and checks if it is True or False. If the condition evaluates to True, only then the loop runs. If the condition evaluates to False, the loop breaks. In order to repeat the loop infinitely, you can use :

while True :

It works because, when the given condition gets evaluated, it will return a boolean value.
