Please tell me they got rid of using underscores and double underscores. That is why I never really got into python, I see that in the code listings and it pushes me away.
[font=courier new][size=8pt]Here is a program that does exactly the same thing as the thinBasic script, here:
http://community.thinbasic.com/index.php?topic=3403.0
Only, this one is written in Python 3.
(Python 3.x is not necessarily backwardly compatible with Python 2.x.)

[font=courier new][size=8pt]I'd like to be able to tell you that, Kent, but I don't think I can.
I don't like any kind of underscores.
For instance, I don't like the identifier, "long_black_train".
One thing I like about Lisp, is that you can have dashes ("-") in names. And, the language uses them for its library functions. So, you could have the identifier, "long-black-train".
For my own identifiers, I never make one that requires me to use the shift key. And, I don't know how to type, either. I use only one finger from each hand. And, normally, I never indent any code (Python forces you to, but, I got the Wingware Personal Python IDE ($35), and it does it for you).
I do remember that Python uses built-in identifiers, like, "__self__", (4 underscores). I agree, they test your patience.
Some languages force you to use mixed case, like, "openWindow" (Java). That is almost beyond my capacity.
Here are the changes in Python 3.0.

Looks like they removed some underscores and put them back in other places, too bad.

_I_ use a few of these scruffy beasts in Oxygen for system variables and labels. Normally you will never see them. The underscores are there to prevent conflicts with user defined names.

I know Charles, that is what Python does too to some extent. I would rather see something like sysName instead of _Name_ or resName for reserved or even them spelled out systemName or reservedName a lot easier on the eyes if you ask me. Look at this code from python, yikes!
[code=python]>>> class MyClass():
... def __init__(self):
... self.__superprivate = "Hello"
... self._semiprivate = ", world!"
...
>>> mc = MyClass()
>>> print mc.__superprivate
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: myClass instance has no attribute '__superprivate'
>>> print mc._semiprivate
, world!
>>> print mc.__dict__
{'_myClass__superprivate': 'Hello', '_semiprivate': ', world!'}[/code]
