If you simply want to compile a file or group of python files from the terminal, the py_compile module can run as a script as follows:
python -m py_compile file1.py file2.py file3.py
Actually, to run a python file, you do not have to compile it. Python is an interpreted language, and you can run scripts directly from the terminal:
python hello.py
But you can also make the executable file by adding the #!/usr/bin/env python directive to the beginning of the file and launching the command from the terminal:
chmod +x hello.py
Once this is done the file is executable and to execute it just type:
./hello.py
