Hi Andrew,
I'm sure the exercises at the end of the each chapters are there for you to
attempt. Asking for help here without attempting it is not the best way to
learn.
If however, you've tried something - and it didn't work, by all means ask
for help.
In the mean time show us what you have so fa

Thereis adfference between "works properly" (ie does what it should) and

You need to read up a bit more on boolean expressions
flips=0
h='heads'
t='tails'
while True:
flips+=1
Ali,
I am new at this but here is my interpretation.
1) flip coin 100 times, and print out the number of heads and number of tails.
from random import Random
score = [0,0]# first position will be heads and second position will be tails
count=0#counter to find out how many times we have flipped.

Chris,
Thanks for your well-written reply. Your analogy to the
complexities of other special methods is well noted. I'll accept
the "small price for flexibility" that you note, if necessary.
However, I still desire a cleaner solution.
I can examine the inherited slots to see which sp

ISTM that in general B.__deepcopy__() should call
A.__deepcopy__() to do the "A" part of the work. In your example,
this won't work because

I got rid of that portion of my site. All that's there now is the e-book
