Python upgrade does not work

Question

I'm trying to update from Python 3.6.8 to Python 3.7.

I followed these steps:

1. sudo apt-get install python3.7 

2. sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 1 sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.7 2 

3. sudo update-alternatives --config python3 

   and choose Python 3.7

4. Check the Python version using python3 -V. It shows Python 3.6.8.

What can I do?

Try to locate the binary for your python 3.7 installation using either of the following.

locate python 

or

sudo find / -type f -name "python3.7*" 2>/dev/null 

If you are able to find the right executable, you might need to add it to your PATH environment variable. Otherwise, there might have been some other sort of issue with the installation.
