When I run Gspread with Python3, I get this error:

ImportError: No module named 'gspread'

When I run with just Python, I get no errors. I installed gspread with pip install gspread --user. I really need to use Python 3, and I expect I should be able to, but I just did something wrong.
You have to install pip for python3 using apt install python3-pip
Then you can install using pip3 install gspread --user
