Hi tutors.
Is there a way to remap a tab key to enter a user-specified number of spaces in
a Tkinter text widget instead of a genuine tab? An internet search has turned
up zilch. The tab option in a text widget lets you enter the number of
centimeters to space over, but this option is truly use

based on the all the performance questions, i would say agree that
dictionary access is faster than lists (hashes exist cuz they're fast)
but they use up more memory, as shown in shawn's numbers. also, one of

Here is an interesting result with defaultdict(set). This program creates 2
dictionaries of sets with the first dictionary containing 10 elements per set
and the second containing 25 elements. You'll see the sets in the first
dictionary are unordered and in the second they are ordered.

Hello again,
I just tried with the classmethod() built_in function. Well, this is
exactly what I was looking for. It supplies a way of defining type_level
methods -- what was missing before.
[I still think this is a workaround: we would not need this if the
syntax was the same for methods and

Seems like when they press "op" you assume that the current number is
done being executed and save the value. Then when they press another
op, you evaluate the previous op with the new value. You don't update
the display until they start typing again.
However, when they press =, you evaluate the
