Trying to change python2 to python3 on the terminal

Question

I was trying to install a new module when the problem appears. I was trying to use python3 but still have python 2.7 version. I've changed to /bin/zsh in the settings. Tried brew install python3. Finally, I've came with sudo update-alternatives--setpython/usr/local/bin/python3, but I couldn't type my password, as I was trying to type symbols, nothing happens.I see only a key near the password line(can't show it). Nothing registered. Like my keyword is broken or something. I am using MacOs Catalina. I will be very grateful if you you help.

First of all, seems you fail at your password here. Second, I think update-alternatives is a linux command, that won't work for OSX. — fpietka

Also, passwords don't appear, but the characters still get registered. — Mythreyi

Type which python3 to check if it's installed. If it is, then you can just start using python3. If it's not installed, brew install python will install the latest version of Python, which would then be accessible using python3. — Mythreyi

Typing in the password happens without visual feedback With Homebrew you can try this:

$ brew install pyenv

Then install the latest Python3 version and set it for your zsh:

$ pyenv install 3.8.5
$ pyenv global 3.8.5
$ echo -e 'if command -v pyenv 1>/dev/null 2>&1; then\n  eval "$(pyenv init -)"\nfi' >> ~/.zshrc
$ python -V

in a macOS Terminal, type or paste: /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)" or what is your problem now?
