Re: some problems for an introductory python test

Python is a little looser about whitespace than one might expect from
reading 'normal' code when the result is unambiguous in that it cannot
really mean anything other than what it does. Two other examples:
>>> if3: print('yes!')
yes!
>>> [0] [0]
0
Not sure what you mean here - is it a joke? The first looks like an if
statement, but isn't. The missing space *does* make a difference. (Try
"if0" instead.)
The second is normal indexing, which allows white space. I wouldn't
consider that surprising, but maybe I should? (Honest question, I really
don't know.)

Re: best way to remove leading zeros from a tuple like string

If I decide I need the parentheses, this works.
"(" + ",".join([str(int(i)) for i in s[1:-1].split(",")]) + ")"
'(128,20,8,255,-1203,1,0,-123)'
Thanks,
Bruce
Creating the tuple seems to be even simpler.
>>> str(tuple(map(int, s[1:-1].split(","
'(128, 20, 8, 255, -1203, 1, 0, -123)'
