In Python print() and time.sleep() are only called for their side effects and pause execution for seconds? What does it mean?

Question

some deep knowledge of python

Answer 1

time.sleep() halts the program while print() outputs a string, char, float, int or bool to the console window. I'm sorry I don't understand the question. Time.sleep() is used for its side effects (halting a program for a certain number of seconds).
