Question

Is it valid to declare integers in Python in the form int x; rather than x=0? Because Im trying to setup a recursive function and using using x=0 resets the value of x each time. Any inputs would be great

Answer 1

And here is a link to the code that I've written so far: http://ideone.com/EImiV

Answer 2

you can instantiate a variable by using int x, but I don't think that will solve your problem. You can declare global variables in Python, check it out: http://docs.python.org/release/2.4/ref/global.html, see also section 6.13 here: http://docs.python.org/release/2.4/ref/global.html

Answer 3

also, you shouldn't instantiate a global variable inside of anything else. You can then assign values to the global variable inside other objects, but you'll need to re-instantiate it, e.g., global x

Thanks for the reply, so does this serve the purpose:

Answer 5

here is what i get when i try to use "int pointer"

idle is great for trying things out before you use them

does your second post work? it doesn't look like it is recursive.

Answer 6

@bwCA, thanks for the reply!
I just got access to IDLE and the second version throws this error:'break' outside loop.
And I think the subrecfn() is being called recursively.

Answer 7

a recursive function calls itself

Answer 8

@bwCA, I've rewritten the code as below,

is this a valid approach? I've been stuck with infinite loops for a while now

Answer 9

when you run it, it prints the target - is it changing the way you want/expect it to?
I suspect line 15 is the source of the infinite recursion.

it is close
if you are going to use count as a global variable you need to initialize it outside the function and put the global statement inside the function
