All members are camel case, right? Why True/False but not true/false, which is more relaxed?
You mean intended? :)

I'd change it, then again I find that typo too amusing:)

It's a standing in-joke, not a typo.

Yes, but I mean the guidelines. Does it make sense to use pascal casing if the default members are camel cased?

A:
Form Pep 285:
Should the constants be called 'True' and 'False' (similar to None) or 'true' and 'false' (as in C++, Java and C99)?
=> True and False.
Most reviewers agree that consistency within Python is more important than consistency with other languages.
This, as Andrew points out, is probably because all (most)? built-in constants are capitalized.

Thanks James, but isn't the default casing is camel casing in python?

It is for classes. There are different rules for other things.Scroll to "Naming Conventions": http://www.python.org/dev/peps/pep-0008/

A:
Here's a possible explaination:
I see that naming conventions are such that classes usually get named CamelCase. So why are the built-in types named all lowercase (like list, dict, set, bool, etc.)?
Because most of them originally were types and factory functions, not
classes - and a naming convention is not a strong reason to make backwards incompatible changes. A different example: the new builtin typesetis based on (altough not exactly equal to) the Set class from the sets module

A:
All of python's built-in constants are capitalized or [upper] CamelCase:
Andrew Jaffe

@Kev, yes, but technically, I think "upper CamelCase" is the same as PascalCase.

You mean like with None and Ellipsis, the other built-in named literals?

Actually more for things like len, str, bool, etc, but having to capitalise these constant, just makes it slower to type.

`len`, `str`, `bool` etc are [builtins](http://docs.python.org/library/functions.html), which are all lowercase.. I don't see how Python is inconsistent..

A:
True and False are capitalized in Haskell, the other language which uses indentation as syntax.
