Python increment pulling from an array in a loop -

i trying create would

• read file
• separate ever thing array
• use first string in array , something
• after done go second array , something
• keep repeating process until array done.

so far have

users = open('users.txt', "r") userl = users.read().splitlines() 

what want open text file, separated 1 line per string, have python part put array, first string , set variable. there variable used in url xbox.com.

after checks have json read page , see if gamertag list have being used, if being used go array , go second string , check. needs constant loop of checking gamertags. if find gamertag in array (from text file) isn't used, save text file entitled "available gametags" , keep moving on.

what want (requested in comments)

• open program
• have read text file of usernames have created
• have program test each program @ end of gamertag viewer link xbox
• json read page , if contains info name taken goes list , uses next gamertag on page.
• keeps doing this
• logs gamertags worked , saves text file.
• exits

the problem in doing don't know how go file , access line after 1 tested , continue pattern until file read.

use loop:

with open("users.txt") f:     line in f:         # whatever line 

for example, achieve goal here, might this:

# import our required modules import json import urllib2  # declare initial variables input_file = "users.txt" output_file = "available_tags.txt" available_tags = [] # empty list hold our available gamertags  # open file open(input_file) input_f:     # loop through each line     line in input_f:         # strip new line character line         tag = line.strip()         # set our url , open connection api         url = "http://360api.chary.us/?gamertag=%s" % tag         u = urllib2.urlopen(url)         # load returned data json object         data = json.loads(u.read())         # check if gamertag available         if not data['gamertagexists']:             # print , add our list of available tags if             print "tag %s available." % tag             available_tags.append(tag)         else:             print "tag %s not available." % tag #otherwise  # check have @ least 1 valid tag store if len(available_tags) > 0:     # open our output file     open(output_file, "w") output_f:             # loop through our available tags             tag in available_tags:                 # write each 1 file                 output_f.write("%s\n" % tag) else:     print "no valid tags written output file."
