Pip3 question: Issues

Python
1

In the Pip lesson (Beginning), the Mosh says:

~ $pip3 install requests

But where? Am I supposed to be in a specific folder for this? Where is Requests installed to?

General comment: When Mosh is talking about Python code features, he’s pretty clear but when it comes to the setup on the computer, not so much. Am I supposed to be in the Terminal, or in cmd? and in a specific folder? Or what?

For instance, I have a folder in my Python directory, HelloWorld, but…so what?

They are installed globally unless you are using virtualenv.
If you want to know where the package is installed see:
