ok, someone has to be the bad guy and show an example of equivalent code that's more difficult to read:choice([use_for_float_demo, use_for_integer_demo])() seriously tho, the bottom line of what people have been telling you is that for the function (or method) foo(): def foo(): : there is a distinction between: foo and foo() in the former, you have a function object. it's just like any other Python object, but with one heaping distinction: it's callable -- this means that u can slap on a pair of parentheses after the object and execute it, which is what i did after calling choice() above to pick one of the 2 functions, then *calling it* with the trailing "()". in the latter, you've not only picked out a function object, but have also executed it as well. that's why when you had choice([a(), b()]), you see the results/output from a() and b() -- you called both, got both return values, and asked choice() to pick one of the 2 return values!! and since you throw away the return value, it didn't matter which one came back because both had executed.
Thanks, Wes, for the further clarity. Dick _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
