Hi John, and welcome. My responses interleaved between yours below.

Python only has one syntax for calling anything, and that is to put parentheses (round brackets) after it, with any arguments needed inside the parens. So this is how you would call the path: path() But that's not going to do you any good, since path is surely going to be a string, and strings aren't callable: you'll just get a TypeError: py> path = "directory/file.txt" py> path() Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: 'str' object is not callable So would you like to clarify what you actually mean by "call the path"? > Below, my code is calling the input file, but not the path. > > Sorry for the inconvenience and thank you for your time. > > > import sys > path = sys.argv[1] > y = map(str.lower, path.split()) I *think* what you mean is that you have a python script, let's call it "script.py", and you run that script like this: python script.py and now you want to add a path (a path to what? a file?) as a command line argument: python script.py /some/directory/file.txt And then what is supposed to happen? I'm going to guess that you want to take the argument given: path = "/some/directory/file.txt" and do something to it, not sure what. Perhaps normalise the case? import os path = os.path.normcase(path) should do what you want. You can read up on the functions available in the os.path module here: For version 2: https://docs.python.org/2/library/os.path.html For version 3: https://docs.python.org/3/library/os.path.html -- Steve _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
