Iterating over multiple lists (a newbie question)

[Victor Muslin]

Thank you all for the insights. Here is another variation on the them,
though this involves a single list.

Suppose I want to parse command line arguments (never mind getops,
since this could be some other situation not involving command line
arguments). Here is how I could possibly parse command line arguments
for command: "myprog -port 10 -debug":

	import sys
	debug = port = 0
	i = 1                                      # ugly
	while i < len(sys.argv):
	    if sys.argv[i] == '-debug':
	        debug=1
	    elif sys.argv[i] == '-port':
	        i = i + 1                          # ugly!
	        if i < len(sys.argv):           # very ugly!
	            port = int(sys.argv[i])
	    i = i + 1                              # quite ugly

Pretty ugly, huh? Is there a more elegant way?
