Re: [Tutor] Why is this only catching one occurance?

[Chris Hengge]

That was supposed to say "Thanks for this" but I was in a hurry.

Anyways, here is my solution:
# Remove any copies of .hex that aren't BMC
        for foundItem in directoryList:
            try:
                if ".hex" in foundItem.lower():
                    if "bmc" in foundItem.lower():
                        wantedList.append(foundItem)
                    else:                      
                        print foundItem + " removed!"
                else:
                    wantedList.append(foundItem)
            except:
                print "Failed to strip excess hex files."

You're removing stuff from something you're iterating over!
*slaps your fingers with a ruler*
Make a copy of the list!
