Shell is selecting Python 2.7, but not 3.7

I have Python 3.7 and I had a Python 2.7.

But when I am using Python Launcher it uses 2.7 not 3.7.

How to use Python 3.7? OS - Mac OS.

In the Python Launcher menu, go to Preferences. You should see a text box called "Interpreter", in there insert the path to your python 3.7, for example:

/Library/Frameworks/Python.framework/Versions/3.7/bin/python3

You might also add that to your PATH environment variable and use python3 (and idle3) rather than plain python.

There are several ways you can obtain this behavior, my preferred one is symlinking the python3 executable to python

sudo unlink /usr/bin/python
sudo ln -s /usr/bin/python3 /usr/bin/python

Another way would be using pyenv https://github.com/pyenv/pyenv

Be aware od the fact that if you do this and you have some scripts on your machine that use the shebang #! /bin/python and were written for py2, they may stop working

If you want python 3.7 as default when you run command python in terminal, you can add an alias in ~/.bashrc 

alias python=python3.7

bashrc is a shell script that bash runs whenever it is started interactively. You can find bashrc in your home directory.
