python - How to set the default python3 to python3.7?

Question

I have a Python 3.6.8 in /usr/local/bin/Python3 and a Python 3.7.6 in /usr/local/bin/Python3.7 on my Macbook (In addition, there is Mac default Python2, which I don't want to change it).

By check which python3 or python3 --version, I can see the current default version is Python 3.6.8. I'd like to set the default Python3 to Python 3.7.6. How can I do that?

You can use the "ln" command to create a symbolic link (symlink) to the existing file as:

ln -s -f /usr/local/bin/Python3.7 /usr/local/bin/python

In order to be sure you can close your terminal and then open it again to check the changes default version as before.

python3 --version
