for line in file weirdness

[SamIam]

I think what you need to do is to have a nested if_else statment:
for line in filelines:
        if some_condition : break
        else: do_something_else

If the if statment is excuted then break return to for_loop
else do something different then return to for_loop.
    When I read from a file I read the whole file into a variable then
work form the variable

file = open('InputString','r')                              # open file
for reading only
filelines = map(string.strip,file.readlines())      #remove newlines
for string

Then you can just use the variable filelines and loop through as much
as you like. If I can help you can email me at servando at mac.com

Hope this helped.
