Tips

After the first compilation of the installation, it is possible to find that the arrow keys fail after the input python3.6.

The reason is that the ReadLine library is not installed.

sudo apt-get install Libreadline-dev

Once installed, then recompile the Python installation once.

CD Python-3.6.0./configuremakesudo make install
