how do i take unlimited sys.argv[] arguments?
Question: To elaborate, I am interested in learning how to code out in python a
sys.argv[] function that allows the user to supply as many arguments as the
user wants. I am unsure on if there is a better way to do this or if it can be
done at all.

The point to this is to develop a similarity tool between text docs of various
size and quantity. the use case in this situation takes as little as argv[1]
and as many as argv[unlimited].

Any input, sources, or advice is welcome.


Answer: `sys.argv` is just a regular Python list, so you can just ask `len(sys.argv)`
for example, or you can just enumerate the contents directly (using a `for ...
in` loop) as with any other iterable.

Note that `sys.argv[0]` is the name of the program, so you need to skip the
first item. (It then follows that `(len(sys.argv) - 1)` is the number of
arguments supplied by the caller.)

    
    
    import sys
    
    for arg in sys.argv[1:]:
        print arg
    

Example invocation:

    
    
    $ python test.py a b c
    a
    b
    c
    

In your case you would replace `print arg` with whatever processing you wanted
to do on the argument.

This will work up to any operating-system-imposed limits. (Some OSes limit the
number of arguments you can pass to a program. For example, on Linux you can
see these limits with `xargs --show-limits`.)
