Threading
The threading module allows multiple threads of execution to take place in a Python program.
While threads may appear to run simultaneously, only one thread can be executed at a time. This is enforced by Python’s global interpreter lock.
Threading is helpful when working with tasks that are I/O bound. This includes web-oriented tasks like scraping or downloading files.
Syntax
