Extending Python with third-party packages (example: numpy)

Показать описание
In this video, I show how we can extend core Python with third-party packages (i.e., functionality that is not included in the standard library). We look at the example of numpy and review PyPI, the primary source for third-party packages in the real world.

PYTHON BOOK
The lecture is based on the free book "Introduction to Python & Programming".

Thanks for the video :)
I have a few questions haha.
Will the !pip install command use your OS to create a new folder inside your python installation? And if so how does it know where to install it to? And how does the import statement know where to load the module from into memory? (i.e. when the current working directory is different from the file location) I assume it has to be some sort of relative mechanism as I as a user can individually determine where to initially install the anaconda distribution/ original python distribution.
