[Tutor] creating the equivalent of string.strip()

[Andrew James]

I've gone ahead and created a script that does this, however it also 
strips punctuation. I was originally just comparing each character to a 
string containing a single space ' ' but even using s[-1].isspace() I 
lose punctuation marks. Any idea why that's happening?

(Not the OP, I just thought this would be interesting to do)
