What is the advantage

Question

What is the advantage of importing specific functions from a module instead of importing a module as whole.

import <module name>
????????????????!!!??????????????????????????
From <module name> import <functions in that module>

Answer 1

There are two reasons in favor of using import module rather than from module import function . First is the namespace. Importing a function into the global namespace risks name collisions. Whether you import a module or import a function from a module, Python will parse the whole module.

Answer 2

Python timeit() is a method in Python library to measure the execution time taken by the given code snippet. The Python library runs the code statement 1 million times and provides the minimum time taken from the given set of code snippets.

Answer 3

Does the execution time of the program decreases?
