Hobbyist - Python vs. other languages

I have been playing with computers since I first learned to program moving shapes on an Atari 800XL in BASIC. After many years of dabbling in programming languages as a hobbyist (I am not a computer scientist or other IT professional), I have never found a way to stick with a language far enough to

simple problem with lists I am just forgetting

Lets say we have this list: funlist = ['a', 'b', 'c'] and lets say I do this: if funlist[4]: print funlist[4] I will get the exception "list index out of range" How can I test if the list item is empty without getting that exception? -- View this message in context: http://www.nabble.co

Re: simple problem with lists I am just forgetting

Alexnb: > How can I test if the list item is empty without getting that exception? In Python such list cell isn't empty, it's absent. So you can use len(somelist) to see how much long the list is before accessing its items. Often you can iterate on the list with a for, so you don't need to care of

find and replace with regular expressions

I am using regular expressions to search a string (always full sentences, maybe more than one sentence) for common abbreviations and remove the periods. I need to break the string into different sentences but split('.') doesn't solve the whole problem because of possible periods in the middle of a

Re: Case tagging and python

Hi, I came up with the following procedure ALLCAPS = "|ALLCAPS" NOCAPS = "|NOCAPS" MIDCAPS = "|MIDCAPS" CAPS = "|CAPS" DIGIT = "|DIGIT" def test_case(w): w_out = '' if w.isalpha(): #se la virgola non ci entra if w.isupper(): w_out = w.lower() + ALLCAPS r

Re: Case tagging and python

I second the idea of just using the islower(), isupper(), and istitle() methods. So, you could have a function - let's call it checkCase() - that returns a string with the tag you want... def checkCase(word): if word.islower(): tag = 'nocap' elif word.isupper(): tag = 'al
