Try changing this:

if not os.path.exists("keyval"):

to this:

if not os.path.exists(keyval):

You've defined keyval as a variable but you're then passing the string 'keyval' to the function.

Also you need to change your boolean values to have uppercase first letters (true = True, false = False)

EDIT: Are you definitely calling the main() function? Try adding the following to the bottom of your code and running (outside of any functions);

if __name__ == "__main__":
    main()
