Help with "getopt" module

[fastfusion]

I really need help with the getopt module.
I'm trying to follow the "Blackhat Python" book and I am trying to make a Netcat replacement.
In it, I need to parse the command line arguments:

 opts, args = getopt.getopt(sys.argv[1:], #this part I dont understand) 

How do I use that part to my advantage? Please someone help!

Sys.argv is a list which holds the all command line arguments.
Because its first element is the script's name the actual arguments start from index 1. [1:] part is called slicing. It means get the list elements from index 1 to the end.

I would use the argparse module instead. It is much better.
