Thanks for that Fredrik, that's clear. That's actually a pretty nice feature as it's nicely optimised. >>> a = 10 >>> c = 10 >>> a is c True >>> c = c +1 >>> a is c False >>> Cheers, Tony -- http://mail.python.org/mailman/listinfo/python-list

where are isinstance types documented?

2006-09-26 Thread codefire
Hi, I'm using the isinstance built-in function. I've found the docs for it, but there are no docs on the supported types. For example isinstance(a, int) works fine but isinstance(s, string) doesn't - because 'string is not known'. I do know how to import the types module and then use defined typ

Haha! OK thanks guys. I was just trying to check if objects were the same (object), didn't know Integers were a special case. Thanks, Tony -- http://mail.python.org/mailman/listinfo/python-list

Surprise using the 'is' operator

I thought the 'is' operator was used to identify identical objects, whereas the '==' operator checked equality. Well, I got a surprise here: IDLE 1.1.3 >>> a = 10 >>> b = a >>> a is b True >>> a == b True >>> c = 10 >>> a == c True >>> a is c True >>> I was NOT expecting the last statement to ret

Might be handy to point out that the Python version will be easier (and therefore cheaper) to maintain compared to the Perl version. As someone said there are numerous success stories at python.org. You could also point him at : http://www.tiobe.com/tpci.htm Although Perl is higher than Python (

Yes, I didn't make it clear in my original post - the purpose of the code was to learn something about regexps (I only started coding Python last week). In terms of learning "a little more" the example was successful. However, creating a full email validator is way beyond me - the rules are far too

Hi, thanks for the advice guys. Well took the kids swimming, watched some TV, read your hints and within a few minutes had this: r = re.compile(r'[EMAIL PROTECTED]@\s]+\.\w+') This works for me. That is if you have an invalid email such as tony..bATblah.com it will reject it (note the double do

Hi, I am trying to get a regexp to validate email addresses but can't get it quite right. The problem is I can't quite find the regexp to deal with ignoring the case [EMAIL PROTECTED], which is not valid. Here's my attempt, neither of my regexps work quite how I want: [code] import os import re
