Why would I get a TypeError from the len function?
the problem is, that (1,len(a)) is evaluated, neither what type a

What's the best way to count number of items in a list?
For instance,
a=[[1,2,4],4,5,[2,3]]
I want to know how many items are there in a (answer should be 7 - I don't
want it to be 4)
I tried:
b=len([x for y in a for x in y])
That doesn't work because you would get an iterat
I tried this and I got:
[(1, 'a'), (2, 'b'), (3, 'c')]
But if I change:
a=[1,2]
I got:
[(1, 'c')]
Why is that? I thought I should be getting:
[(1, 'a'),(2,'b')]
?

What did you expect the "length" of the integer 3 to be?

That's *it*.
So, how would you overload an operator to do:
With native complex support:
def twice(a):
return 2*a
print twice(3+4j), twice(2), twice("abc")
Let's presume for a moment that complex is *not*

How long is a piece of string? There are many different ways, which
give you different trade offs.

Sorry if my question was a little "lazy" and yes, I was asking about the
"lazy evaluation". :=)
I am surprised about this (and this can be dangerous, I guess).
If this is true, I would run into trouble real quick if I do a:
(1/x,1.0e99)[x==0]
and that's not good.
Something to keep in mind. :
