Re: Parse each line by character location

recno_idx = slice(0,10) client_idx = slice(10, 11) volume_idx = slice(11,11+10) order_type_idx = slice(11+10, 11+10+3) . !? That seems to me confusingly far from a working solution, at least in comparison to recno_idex = the_line[0:10] client_idx = the_li

[2.5.1] Building loop with some exceptions?

Hello I need to call a URL through a loop that starts at 01 and ends at 99, but some of the steps must be ignored: = url = "http://www.acme.com/list?code="; p = re.compile("^(\d+)\t(.+)$") for i=01 to 99 except 04, 34, 40, 44, 48, 54, 57, 67, 76, 83, 89: f = urllib.urlopen(url + i)
