questionable questions and a lazy way to add command line support to a Python module


I just took this Myers-Brigg questionnaire and I just "love" (sarcasm) some of these questions:

Do you usually get along better with imaginative people, or realistic people?

What? Truly imaginative people have to be "realistic" otherwise they're just spewing out pipe-dreams. People who can think of the new and make it a reality have to have a large degree of realism.

In reading for pleasure, do you enjoy odd or original ways of saying things, or like writers to say exactly what they mean?

First of call, I question why the question is making some kind of statement as to writer, not the book or the "message", as the basis for selection.

Secondly, show me a writer who thinks they are saying "exactly" what they mean and I'll show you a "writer" who knows not one thing about interpretation of the self let alone the words of others.

Anyway …

Ok, on to the second thing I wanted to say before I jump in the shower past noon (I'm home … say it with me … sick).

I have a Python module with lots of functions. I want them to be importable in other Python scripts AND callable via the command line.

And I want them all callable via the command line without taking the time to write out command line option support.


For example, in a script with a function "echo" that prints an argument, "add" that adds two integers, and "times" that multiplies two integers, I just want to do this:

$ python echo('hello world')
hello world

$ python echo(add(1,2))

$ python echo((add(100, times(2,10))))

instead of stuff like this:

$ python --function=echo arg="hello world"

etc. …

Using the built-in "eval" function and "sys.argv" seems to be working:

def echo(s):
  print s

def add(x, y):
  return x + y

def times(x, y):
  return x * y

def main():
  import sys
    funks = sys.argv[1:] #user must pass strings in single quotes. 
    funks = " ".join(funks)

if __name__ == "__main__":
