The Python Makefile must use the file python_program.py to create an executable file called python_program.

Assume that your Python Makefile is called Makefile.python and is in the same directory as the python_program.py, and therefore, when you run make -f Makefile.python in that directory, your Python Makefile will create a python_programexecutable.

Also, your Python Makefile must recreate python_program when python_program.py changes.

#!/usr/bin/env python def main(): print("Hello world from Python") main()
