While True and While 1 Is infinite loops in perl and Python. In most cases, python acts as though True equals 1. In Python 2.x, True is not a keyword, but just a built-in global constant that is defined to 1 in the bool type. In Python 3.x it truly becomes a keyword and a real constant. With the "while True" loop, e,g. it constantly refreshes and constantly prints out the mouse position. 

===============================================

A while loop that continuously prompts the user to input their name. If the input matches the string "Yougui", the loop will break. Otherwise, it will continue prompting for input. Here's a breakdown: (code):  

Output: 

============================================  

A while loop that continuously prompts the user to input their name. If the entered name is not equal to "Yougui", it uses the continue statement to skip the rest of the loop's code and goes back to the beginning of the loop to prompt for input again. If the entered name is "Yougui", it breaks out of the loop (break), ending the program. (code):
