linux – Does Python have an argc argument?
In python a list knows its length, so you can just do len(sys.argv) to get the number of elements in argv.
I often use a quick-n-dirty trick to read a fixed number of arguments from the command-line:
[filename] = sys.argv[1:]
in_file = open(filename) # Dont need the r
This will assign the one argument to filename and raise an exception if there isnt exactly one argument.

Youre better off looking at argparse for argument parsing.

Just makes it easy, no need to do the heavy lifting yourself.
