You left out 3CPO, Dave.
Names with numerals are not unreasonable in some circumstances.
But programming languages are not a full spectrum of real life. They can have
reserved words too so you may not be able to use "while" and if you choose to
create a function that masks another, you cannot

Yes (once formatted for Python).
If so, how to change to EAFP?
Not sure if can. Let's alter the code to:
foo = 0
#and
def do():
return 5 / foo
Then, you will expect a ZeroDivisionError
This is not what @Avi menat by "silly variable names" but:
3D_position
2nd_floor_area
3M_PostIt_size
3rd_degree_polynomial
360_degree_view
12_hours_later

Thank you for your responses, Sam and Greg.
The do_richcompare function is where my research originally took me, but I
feel like I'm still missing some pieces to the puzzle.
Here is my updated research since you posted your responses (I'll attach a
pdf copy too):
Boy do I hate when I see my code mangled by the stupid AOL mailer.
Not that anyone cares, but the code should be read with each line starting with
the "> " prompt.
If I leave lots of blank lines, it may work, but as the illustration is not in
python, I will now remove the prompts:

Bryan,
As has been pointed out, it is very common in possibly all programming
languages to not allow digits at the start of many identifiers. It makes it
hard to parse for numbers which tend to start with digits. Some languages even
have special rules on not starting a number with a zero unless

The name of an attribute must be an identifier. An identifier cannot
begin with a decimal number.

You probably want something like overload/multiple dispatch. I quick search
on PyPI yields a 'multipledispatch' package.
I never used, however.

If the queue was not shared to any other process, I would guess that its
size is reliable.
However, a plain counter could be much simpler/safer.
The developer of multiprocessing.Queue, implemented
size() thinking in how to share the size and maintain a reasonable
consistency between process.

I'm targeting HKEY_CURRENT_USER so I assume HK_USERS includes that.
