Symlink python3 command to run python 3.10 (or any latest python versions)

First check which python version you need by running-

$ ls /usr/bin/python3*
/usr/bin/python3    /usr/bin/python3.5-config  /usr/bin/python3.5m-config  /usr/bin/python3.7-config  /usr/bin/python3.7m-config  /usr/bin/python3.10-config  /usr/bin/python3m
/usr/bin/python3.5  /usr/bin/python3.5m        /usr/bin/python3.7          /usr/bin/python3.7m        /usr/bin/python3.10          /usr/bin/python3-config    /usr/bin/python3m-config

Now, to symlink python 3.10 to python, execute the following command in your shell-

$ ln -sf /usr/bin/python3.10 /usr/bin/python3

The above command would have added a symlink of python3.10 to python3. To verify the same, you can run the command-

$ /usr/bin/python3 --version
Python 3.10.2

or even run the python3 command directly to check if the symlink works for Python 3.10-

$ python3 --version
Python 3.10.2

Symlink python3 command to run python 3.10

Similarly to symlink python 3.10 to python, execute the following command in your shell-

$ ln -sf /usr/bin/python3.10 /usr/bin/python3

The above command would have added a symlink of python3.10 to python3. To verify the same, you can run the command-

$ /usr/bin/python3 --version
Python 3.10.0

or even run the python3 command directly to check if the symlink works for Python 3.10-

$ python3 --version
Python 3.10.0

As I've discussed ways to symlink any latest python version to python3 seamlessly, you can symlink to any version of your choice with the above commands.
