sudo make altinstall
4. Make Python 3.7 as the default version
If you want to use python 3.7 as a default version you can create an alias.
Let’s check the path of Python.

which python3.7and then follow the Step 4 again.
/usr/local/bin/python3.7
5. Check Python Version
After creating an alias check the python version again.
python -V
Python 3.7.0
