newbie - How do I import automatically?

[bobueland at yahoo.com]

Where do I put

 def runsource(self, source):
        if(source == ''):
           source = 'from btools import *'
        "Extend base class method: Stuff the source in the line cache
first"
        filename = self.stuffsource(source)

Do I put it in Pyshell.py or somewhere else?
