How to install/call Python Scripts?

[Anonymous]

Could someone please explain the installation of Python scripts?
I've created a simple script w/UI to lock joints during weight painting.
It has 2 procedures:
1) Open the UI - def pixl_jointLocker():
2) Execute a procedure to set the locked state of the joints - def lockEm():
All of the code works.

In my C:\Documents and Settings\Administrator\My Documents\maya\2010-x64\scripts\userSetup.py with this line:
import maya.cmds as cmds

I invoke the script with:

import pixl_jointLocker
pixl_jointLocker.pixl_jointLocker()

The interface appears.
I add joint names to the textFields, press the button which calls lockEm(), and I get:

# Error: NameError: line 1 of <maya console>: name 'lockEm' is not defined #
I've also invoked the script with:

import pixl_jointLocker
pixl_jointLocker.pixl_jointLocker()
pixl_jointLocker.lockEm()

I get the same error.
Thanks.

suppose you have a module example.py that looks like this:

import maya.cmds as mc

def exampleWindow():
 w = mc.window()
 mc.columnLayout()
 mc.button(command='exampleFunction()')
 mc.setParent ('..')
 mc.showWindow(w)

def exampleFunction():
 print ('boo!')

then you could use

from example import *
exampleWindow()

Thanks for the reply.
After some fooling around w/the import and reload commands, I'm moving forward.
