find hidden python files

[bobsmith76]

I have a built-in operation which is eating up 74% of the run time in my code and I'm having a very difficult time tracking down its location. If look at the pictures you'll see that there is an operation which is simply called __call__ and its located at line 394 of the reference.py file. Then you'll see the number 20 circled, that means 20 seconds and the program takes 33 seconds so that's how much time this operation is taking up. Then below that you'll see the four lines that use this feature and one of them is in _xlmac.py file. I cannot find either the _xlmac or the reference.py file. I think because they are hidden. If you put in those names into the mac spotlight those files do not come up.
