Re: regular expressions.
Use the print statement: import re vowel = r'[aeiou]' print re.findall(vowel, rvowel) Alexey On Fri, Aug 8, 2008 at 2:17 PM, Atul. [EMAIL PROTECTED] wrote: Yes.

Re: regex question
No, there is a bad way - because of the example doesn't solve arbitrary amount of number.number.. blocks. But the python regexp engine supports for lookahead (?=pattern) and lookbehind (?=pattern). In those cases patterns are not included into the replaced sequence of characters: re.sub('(?=\d)\.(?=\d)', '', '1234.324 abc.100.abc abc.abc') '1234324 abc.100.abc abc.abc' Alexey On Tue, Aug 5, 2008 at 2:10 PM, Marc 'BlackJack' Rintsch [EMAIL PROTECTED]wrote: On Tue, 05 Aug 2008 11:39:36 +0100, Fred Mangusta wrote: In other words I'd like to replace all the instances of a '.' character with something (say nothing at all) when the '.' is representing a decimal separator.

Re: regex question
=) Indeed. But it will replace all dots including ordinary strings instead of numbers only.

Fwd: Unit testing type comparison
Hello Mike, The reason of the problem is that the class Test was not pushed into the sys.modules. Use one more separate module for that stuff: *one.py* class Test(object): '''just define''' *three.py* from one import Test #push one.pyc to sys.modules if __name__ == '__main__': import two two.run( Test() ) *two.py* def run( a ): from one import Test #reuse existing Test print type(a), Test, type(a) == Test Regards, Alexey On Sat, Aug 2, 2008 at 5:16 PM, Mike Wyatt [EMAIL PROTECTED] wrote: I have a problem where type comparisons don't work in a second module when unit tests in the first module are run. In the example below, class Test is declared in one.py. When one.py is executed, it calls a method in two.py that imports Test from one.py. The problem is that the Test object passed into the run method is in the __main__ namespace, while the Test class imported from one.py is in the one namespace. Comparing type(a) and Test returns False, even though they are both Test objects. How can I tweak these modules so that the type comparison returns True? I suppose one solution is to redesign my solution to not compare types, but I would still appreciate a solution for my personal knowledge. one.py class Test(object): pass if __name__ == '__main__': import two two.run( Test() ) two.py *** *def run( a ): from one import Test print type(a), Test, type(a) == Test * *** Output *** *class '__main__.Test' class 'one.Test' False -- http://mail.python.org/mailman/listinfo/python-list -- http://mail.python.org/mailman/listinfo/python-list
