can someone explain this for me?

for count in range(1,11):
        print count

i understand range
i dont understand "for count in"
is count a variable?
if it is a variable how is it "in" range?

You are correct that count is a variable.

Basically:

the code for count in range(1,11) is equivalent to saying: run the following loop for every object in the list created by the range function.

The variable count (or whatever you want to call it) provides a hook into whatever iteration you are currently on.

i.e.:

(Toggle Plain Text)

for i in range(1,5):
   print "i is now: ", i

will give the output:

i is now: 1
i is now: 2
i is now: 3
i is now: 4

------------------

Hope that helps!

Cheers,
