This worked for me.

brew uninstall python3
sudo rm -rf /Library/Frameworks/Python.framework

There shouldn't be the need to uninstall python3.5.

You can just remove it from your $PATH environment variable after you made sure you've installed the latest version via brew install python3.

If echo $PATH looks something the like:

echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Frameworks/Python.framework/Versions/3.5/bin:/opt/X11/bin:/Library/Apple/usr/bin

Then just replace the entry /Library/Frameworks/Python.framework/Versions/3.5/bin with /usr/bin/python3 (the output of which python3). This is done via:

export PATH=$PATH:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/bin/python3:/opt/X11/bin:/Library/Apple/usr/bin

Then it should look like this:

echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/bin/python3:/opt/X11/bin:/Library/Apple/usr/bin

This worked for me after having trouble executing pylint.

It is okay to use python 3.8, as it is backward compatible. So I have just deleted the old venv and created a new venv with current python version, which solved my problem.

tip: Remember to save your requirements into a txt file.

This also happened to me when I was trying to run python3 from iTerm (replacement of terminal). This problem was not occurring with the MacBook's default terminal. After I updated iTerm, this error was not occurring anymore. Please try to update the application on which you are trying to run python3(in my case it was iTerm) instead of updating the python version.
