sys module - argv, but no argc ??

Yes indeed. I felt I needed to comment, however, since one of the
respondents told the OP that len(sys.argv) returns the number of args
passed, and that's not true if you consider args to be those things
passed in addition to the calling script/process.

So does argv in C

Which is also true of argc in C. Python is here mimicking C, which is
what the O.P. wanted. Standard loop:
for (i = 1 /*not 0*/, i < argc, i++) process(arg[i]);
for i in argv[1:]: process(i)
