No, its not correct in python. In python, you don't declare the type of a
variable. You statement above would simply be

NCases = 10.0 / 6.0

Note the float-literals! If you wouldn't use these, the result would not be
~1.6, but 1 instead, because integer division yields only integers.

Depending on which version of python SPSS ships, you should be able to make
the division-operator / enforce the usage of floats by putting


from __future__ import division

on top of your script.

No! That is NOT correct Python. For one thing, you do not declare the
types in dynamically typed languages. Secondly, if you want floating
point division, you need to enter atleast one of the numbers as float.

For example
10.0/6
or
10./6
or
float(10)/6
