[Tutor] Website monitoring program.

[Adisegna]

I need to add the count statement to give urllib access the tuple of urls. urllib needs to be given a different value each time in order to check all the urls. This is the only way I could get the value (web) in urllib to change each time. I tried indenting the count statement and it runs without error but still only makes one pass. 

Thanks

You have to indent the statement 'count += 1' so it is part of the loop. But you misunderstand the for loop - the count variable is not needed at all. Your variable 'i' will receive each element of urls, one each time through the loop. For a simpler example,

 >>> u = ['a', 'b', 'c']
 >>> for letter in u:
 ...   print letter
 ...
a
b
c

So instead of
count = 0
for i in urls:
   web = urls[count]

you can write simply
for web in urls:

See the Python tutorial for more examples of for loops:
