You may need to be a bit clearer. What line of code (or what expression)? What did you expect to see, and what did you see? >From examining your code, I've come up with one most-likely scenario. In Python, indexing is zero-based and, in effect, indexes the boundaries between items rather than the items themselves. Referencing string[-1] actually means asking for the boundary between the second-last and last characters; using that as your end marker actually trims off the last character. What you may want is simply: self.wordList[i][1:] which means "from character position 1 to the end of the string". Hope that helps! Chris Angelico
