Import all Names
The * symbol used with the import statement is used to import all the names from a module to a current namespace.
Syntax:
from module_name import *
What does import * do in Python?
The use of * has its advantages and disadvantages. If you know exactly what you will be needing from the module, it is not recommended to use *, else do so.

# importing sqrt() and factorial from the# module mathfrom math import *# if we simply do "import math", then# math.sqrt(16) and math.factorial()# are required.print(sqrt(16))print(factorial(6)) |
