How to use psspy inside a function??

Hello People,

I defined a function in python which was supposed to do some tasks. Inside the function I was using the API routines but i am getting the error " Name Error: global name "psspy" not defined". This is happening when i am importing a file named temp and using certain parts of it. Without the file temp, it works fine, bust since temp file is an integral part of the whole project i have to use it. Now how do i make psspy run inside the function without getting such an error.

NOTE:- This code is being run through command prompt. That is probably the place where problem lies. When i am running in python shell, the code works fine
