Can't install Python 3 / Jupyter on Catalina properly

Question

I'm trying to install python 3 and jupyter on Catalina.
I installed the latest version (3.7) from Anaconda distribution, but if I type python --version in the command line I get "Python 2.7.16"
If I type jupyter notebook , i get zsh: command not found: jupyter
I have also installed python 3.8.2 from python.org, I thought this might help.
What can I do now to get it running?

Answer 1

try use python3 --version to see if you have python3 installed or not

suggest use brew install python to install python3 https://docs.brew.sh/Homebrew-and-Python

Answer 2

This is the solution for the jupyter problem:

1. cd into your installation directory of anaconda in terminal
   
2. Go into bin folder and drag the binary named conda into the terminal and type init zsh
