What are uses of * module in python and how can I use it ?

Question

Python

Answer 1

Are you talking about this.

from math import *

if yes then here * is used to import all available functions in math module.

Answer 2

Muhammad Abdulmalik

when you use

import math
you have to use math.function_name() syntax to use the function like
print(math.ceil(9.754))

When you use
from math import *
Now you imported all functions of math module . you can now use function name directly like
print(ceil(9.544))

Answer 3

Muhammad Abdulmalik ,

instead of importing a complete module, you should only import the functions / classes that you really need.

sample: you need to round up a number to the next whole number, and you also need the square root function you can do:

from math import ceil, sqrt

Answer 4

Lothar Yes... yes... yes... I 100% agree.

I actually meant to point that out as well and got distracted.

Thanks for stating this. 👌

Ultimately, using * will pollute the namespace and increase the risk of name collision.

Scroll down slightly until you see the example:

from <module_name> import *

* used for multiplication. You didn't see in lesson how to use and where to use?

Are you talking about unpacking lesson where * is used?
