Re: [Tutor] Semantic Error: Trying to access elements of list and append to empty list with for loop

Thanks, everyone, for your help. The objective was to extract all words from each line and place them in a list IF they didn't already exist in it. I sorted it out by adding little bits of everyone's suggestions. Here's the code that fixed it. fname = raw_input('Enter file name:\n') try:
