Pedro - If you are trying to extract a simple pattern like a numeric word followed by an alpha word, I would suggest using one of the scanString or searchString methods. scanString is probably the better choice, since you seem to need not only the matching tokens, but also the location within the

Hello, I'm scratching my head into solving a problem of transforming a POS-Tagged text in a normal text. My biggest problem is that I can't get the quotes to be placed properly. I had tried a different approach but was advised in the nltk list to use this example, but it does not solve the quoting

Re: [Tutor] reading complex data types from text file

All lines that come back from a text file come back as strings. You can use string methods to detect the data like so: f = open('test.txt') lines = f.readlines() numbers = [] strings = [] for line in lines: if line.strip().isdigit(): numbers.append(int(line)) else: strings.

You need to read what dictionaries are. Essentially, any time you think "oh I need to keep separate variables for these values, but I won't know what their names are until runtime!" the correct answer is to not try to manipulate them into variables, but to use them as dictionary keys, or organize t
