Hi Tpc,
I think you're getting too caught up with the word "continue" and its
concept as you use it in human language, rather than what it really does
in the Python language.

hi Alan and Danny,
I think I understand what you guys are saying. I don't believe I am
ignoring the error. Ideally what I'd like is for the procedural
program to run through its steps and if it encounters an error, to log
the error and pick up where it left off and keep going. I gather you

I'm using regular expressions to check if arguments of a function are

Basically, what the regular expression "should" expect is either an

I'm looking for a range()-like function which could generate a list of

pseudorange('aa', 'zz') would generate:

hey guys, so I've been trying to get my head around the try except

This behaviour is not guaranteed and I wouldn't depend on it. It can break if
any other operations have happened on the dict; for example
>>> d=dict(a=1,b=2,c=23)
>>> str(d)
"{'a': 1, 'c': 23, 'b': 2

The following code:
print str(dict(a=1,b=2,c=-1))
print str(dict(a=1,c=-1,b=2))
print str(dict(c=-1,a=1,b=2))
print str(dict(b=2,a=1,c=-1))
print str(dict(b=2,c=-1,a=1))
print
print str(dict(a=1,b=2,c=23))
print str(dict(a=1,c=23,b=2))
print str(dict(c=23,a=1,b=2))
print str(dict(b=2,a=1,c=23))

Thanks guys for your answers, it's clear (even if I wouldn't be able

hi,

I'm learning for almost a year and half python. this is my first language. I'm
fine with classes, definition... But now I'm trying to understand better things
as:
static method
class method
and the use of metaclass.
Does some one of you knows about a compilations of small snippets showi
I have this class:
>>> class A:
... def __init__(self, blank=False, editable=True, name='foo'):
... self.blank = blank
... self.editable = editable
... self.name = name
...
>>> a = A()
>>> a.blank, a.editable, a.name
(False, True, 'foo')
All as expected.
No
Danny and John,
Thanks for the pointers. As I am leaving the project where I need to do this tomorrow, I don't think I will have time to do this, but thanks for the help anyway.

Not just infinite recursion, but recursion that exceeds the maximum recursion
