They both evaluate to false in a boolean context but that is different
from being *equal* to false or to each other.

In [1]: s = ''

In [2]: bool(s)
Out[2]: False

In [3]: s == False
Out[3]: False

In [4]: l = []

In [5]: bool(l)
Out[5]: False

In [6]: l == False
Out[6]: False

In [7]: s == l
Out[7]: False

Re: [Tutor] UnboundLocalError and Break

[Luke Paireepinart]

You're using a global variable (playHP) in a function, but you haven't told
the function that playHP is supposed to be a global variable.You're going to
want to change your function definition to:

def monsAttk (damage, attack): #A monsters attack
*global playHP*
*

That's because Corey originally e-mailed code that he had already modified
rather than the code that was generating the error.  The pastebin code is
different.

Corey, I'm not trying to be an ass, but you're making it difficult for us to
help you and thus we're less inclined to.

Re: [Tutor] help with alternate execution

You top-posted, and sent the mail to me privately (off-list).  That's 
not how mailing lists work.

You added the print, but you didn't look at the result, did you?

So, what was the repr(n) value?  In particular, what is the type of n ?  
Is it what you expected?
