What is the sleep() function and what is it used for?

The sleep() function from the standard time library pauses the execution of the current thread for a specified number of seconds.

It is used for the following purposes:

• Simulating real-time delays.
• Regulating the speed of a loop or operation.
• Waiting for a resource to become ready (e.g., a file, network connection).
• Preventing excessive load on the system or external service.
• Debugging purposes.

import time

print("Start")
time.sleep(2)  # Pause execution for 2 seconds
print("End")
