Question

I ran a python script to create a dict variable based on a database, and then I pickled this variable into disk file for later usage. Now I have a lot of feature classes which all need that variable to create different features. The thing is the dict variable is so large that cannot afford to import multiple times. I am wondering if there is a way I can unpickle and import that variable for only once, and then all feature class can share it?

Python will only import the module once. Any code that executes at load time will only be executed the first time a file imports the module.
