catastrophic regexp, help!
pat = re.compile("(\w* *)*")
this matches all sentences.
if fed the string "are you crazy? i am" it will return "are you
crazy".
i want to find a in a big string a sentence containing Zlatan
Ibrahimovic and some other text.
ie return the first sentence containing the name Zlatan Ibrahimovic.
patzln = re.compile("(\w* *)* zlatan ibrahimovic (\w* *)*")
should do this according to regexcoach but it seems to send my
computer into 100%CPU-power and not closable.

web2py forum or mailing list?
i cant find a web2py mailing list or forum, not by googling and not on the web2py homepage. (yes thats right im asking about web2py not webpy). this framework seems great and i installed and it seems like all i wished for. easy to install, easy to use, fast, etc. just an overall better, complete and more professional framework than anything else out there. do id like to discuss it somewhere, is there such a place? -- http://mail.python.org/mailman/listinfo/python-list

yes, seems very unpythonic though :)
must be a simpler way that isnt slow as hell.

advanced listcomprehenions?
I am wondering if it is possible to write advanced listcomprehensions. For example: """Write a program that prints the numbers from 1 to 100. But for multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz". For numbers which are multiples of both three and five print "FizzBuzz".""" Obv it doesnt have to be a list according tot hat definition but suppose i want to generate that list. >>> [["Fizzbuzz",x] for x in xrange(1,101) if x%3 == 0 and x%5 == 0] [['Fizzbuzz', 15], ['Fizzbuzz', 30], ['Fizzbuzz', 45], ['Fizzbuzz', 60], ['Fizzbuzz', 75], ['Fizzbuzz', 90]] is not what i want. the following does the trick but is ldo not a listcomprehension: for i in xrange(1,101): s = "" if i%3 == 0: s += "Fizz" if i%5 == 0: s += "Buzz" if s: print "%d : %s" % (i,s) else: print i or to generate a lisrt but not by listcomprehsnion: map(lambda x: (not x%3 and not x%5 and "FizzBuzz") or (not x%3 and "Fizz") or (not x%5 and "Buzz") or x, xrange(1,101)) -- http://mail.python.org/mailman/listinfo/python-list
