Let program use command line arguments

[7cardcha]

You know how when you use a command line command you do something like this (I am using the yes command as example)

yes hello

And it will print out hello to infinity. How do you make a program that can take command line arguments?

[cgroza]

It is language dependent. You will have to tell us what language you are trying to do this in.

Python.

[Bachstelze]

Use sys.argv:


import sys
print sys.argv

[Arndt]

Use sys.argv:


import sys
print sys.argv

One can add that the name 'argv' here comes from the old convention in the main function of C programs to let the array of arguments be called 'argv' (v for vector, I suppose).

for more advanced command line handling use argparse (python > 2.7 but its also available as extra package for 2.6) or optparse (python < 2.7)
