Need to use python from an external hard drive

Question

I want to be able to plug in an external hard drive on my computer and use the installed python on it to run my programs. So would I start cmd and cd to the new hard drive? When I installed python I installed it onto the hard drive. I just need to know how I would install new packages and make sure the files I have know the correct path. For example on the hard drive I have a program that runs a webcam with Opencv but I don't have that installed on the hard drive version of python. So how would I install modules and make sure my programs on it use the correct path to use them?

Answer 1

You will want a portable version of python. I myself use WinPython for this.
It lets you open a cmd window within the portable context and then you can pip install and do whatever you would normally do but it wont pollute the current OS
