hello, I´m a student of linguistic an I need do this exercises. Can anybody help me,please? Thanks
Sorry, we're allergic to homework. If you've got any more specific questions about how bits of Python work, do ask, but don't ask us to do your assignments for you. Most tutors can get downright unreasonable about that sort of thing.
◑ Read in some text from a corpus, tokenize it, and print the list of all wh-word types that occur. (wh-words in English are used in questions, relative clauses and exclamations: who, which, what, and so on.) Print them in order. Are any words duplicated in this list, because of the presence of case distinctions or punctuation?
Some questions you should already have the answers to: * How do you identify wh-words? I'm guessing for the purposes of this assignment you've got a list of them. If that's so, look up the bit of the tutorial about finding out whether something is in a list. If you have to parse for them, that's a rather harder problem. * ...but beware of case distinctions -- look up the string methods to see how to play with the case of a string. * Tokenizing the string is just a matter of splitting it up where there are spaces or punctuation. Funnily enough, there's this string method called "split()" that will do this. * What does "in order" mean? In the order in which they occur in the corpus? In alphabetical order? If it's the latter, you'll need to record the wh-words when they occur in a list and sort it at the end before printing it out.
◑ Create a file consisting of words and (made up) frequencies, where each line consists of a word, the space character, and a positive integer, e.g. fuzzy 53. Read the file into a Python list using open (filename).readlines(). Next, break each line into its two fields using split(), and convert the number into an integer using int(). The result should be a list of the form: [['fuzzy', 53], ...].
So you do that. Seriously, this is a pretty complete recipe already. If you can't see how to do it, re-read the tutorial. -- Rhodri James *-* Wildebeeste Herder to the Masses -- http://mail.python.org/mailman/listinfo/python-list
