What is the sleep() function in Python?

The sleep() function in Python is used to suspend the execution of the current thread for a specified number of seconds. It is located in the time module and is useful when you need to pause, for example, to wait for a process to complete or to slow down a loop.

Example of usage:

import time

print("Starting")
time.sleep(3)  # Pause for 3 seconds
print("3 seconds have passed")

During sleep, the thread does not perform any actions, which can be useful for managing execution time or synchronization in multithreaded programs.
