How to import math

I'm a beginner in python and in general programming, and I don't know if these two call for summoning math functions are the same
The short answer:
Use math if you are doing simple computations with only scalars (and no lists or arrays).
Use numpy if you are doing scientific computations with matrices, arrays, or large datasets.
The long answer:
math is part of the python standard library. It provides functions for basic mathematical operations as well as some commonly used constants.
numpy on the other hand is a third party package geared towards scientific computing. It is the defacto package for numerical and vector operations in python. It provides several routines optimized for vector and array computations and as a result, is a lot faster for such operations than say, just using python lists. See the website for more info.
math is a built-in library that is shipped with every version of Python. It is used to perform math on scalar data, such as trigonometric computations.
numpy is an external library. That means you have to install it after you have already installed Python. It is used to perform math on arrays, and also linear algebra on matrices.
Other scientific libraries also define pi, like scipy. It is common not to import math library when you need functions that are only present in numpy or scipy.
If you only need to access pi, you should use the math library.
Moreover, to keep your program light, you should stick with math library.
I just downloaded souder and am looking to use the square root function. I’ve seen that you have to import math or something but can’t find anything else about it. Any help would be appreciated.
