I am writing python scripts and execute them in a Makefile. The python script is used to process data in a pipeline. I would like Makefile to execute the script every time I mak
That's not a lot of information, so this answer is a bit vague. The basic principle of Makefiles is to list dependencies for each target; in this case, your target (let's call it foo) depends on your python script (let's call it do-foo.py):
foo: do-foo.py
python do-foo.py > foo
Now foo will be rerun whenever do-foo.py changes (provided, of course, you call make).
