[Tutor] get a module's own (top_level) dict?
Hello pyhonistas,
Example:
=== module content ===
a = 1
b = 2
==
I'm looking for a way to get something like {'a':a, b':2}. Actually, names
defind in the module will be instances of a custom type. I want to give them an
attribute that holds their own name. E.g.:
for key,obj in dict:
obj.name = key

Are you looking for dir() (built-in function)
dir() -> returns names in current scope
dir(module/class/object) -> module/class/object's attributes

The usual way to do this is to keep an explicit dict of the objects of
interest.
Why do you need objects to know their name? Why can't you tell it it's
name when you create it?

Re: [Tutor] Question
All you really need for python is a basic text editor, and the interpretter. Everything else is icing. Notepad++ has syntax highlighting support for python, and sounds as if it has brace and bracket completion. Most people here will tell you that auto- completion in python is a complex issue (most objects can have dynamic attributes defined at runtime that most auto-complete engines will miss). Notepad++ also supports auto-indentation, which is probably the most useful feature of any editor used for python. Note I've never used it myself, just took a quick look through it's website. --- Richard "Roadie Rich" Lovely Part of the JNP|UK Famille www.theJNP.com (Sent from my iPod - please allow me a few typos: it's a very small keyboard) On 9 Nov 2008, at 03:22 AM, Bap <[EMAIL PROTECTED]> wrote: Can I use notepad++ for Python?

That can be an effective way to catch errors otherwise obfuscated by the browser. Although I don't use windows any longer, I recall that pythonwin was a nice IDE to use and it probably has a syntax checker. tim ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

This can be done with a dict mapping pattern names to types. I don't see how having a pattern know its own name helps here. For example: In [22]: class Foo: : def __init__(self, x): : print "Foo(%s)" % x In [24]: class Bar: : def __init__(self, x): : print "Bar(%s)" % x In [25]: types = dict(foo=Foo, bar=Bar) In [26]: types['foo'](3) Foo(3) In [27]: types['bar'](42) Bar(42) > Also, I want to write the pattern --> name --> type --> object toolset in a > general to be able to reuse it.
