There are lots of way to solve this problem.

The best way is to use the logging module. Here are a couple of 
introductions to it:

https://docs.python.org/3/howto/logging.html#logging-basic-tutorial

https://pymotw.com/3/logging/index.html

and there are many more:

but we can start with something much simpler, just using print.

You have already run:

    fh = open("ML_PY_2.log","w+")

at the start of your program, now call print:

    print("target_names:",target_names, file=fh)

Finally, at the end of your program, call:

    fh.close()
