In Python, a 'parameter' is a function local name defined in the header
of the function and bound to an argument when the function is called.

MD = make directory. Look for this in the os or os.path modules.
Do read the tutorial.

You have an unusual use of the word "parameter". What you are doing is
setting environment variables. You can read these values in Python

import os
outvar = os.getenv("OUTPUT")
logvar = os.getenv("LOG")
completevar = os.getenv("COMPLETED")

# etc
print outvar
print logvar
print completevar

------
You may also want to pass arguments (I think 'argument' is what you
called 'parameter') to your script:
myScript.py firstArg secondArg thirdArg

hunt for sys.argv in the documentation.

For more sophisticated argument passing you may want to look at the
'optparse' module
