"""Hook to allow user-specified customization code to run.
|
||
|
|
|
||
|
|
As a policy, Python doesn't run user-specified code on startup of
|
||
|
|
Python programs (interactive sessions execute the script specified in
|
||
|
|
the PYTHONSTARTUP environment variable if it exists).
|
||
|
|
|
||
|
|
However, some programs or sites may find it convenient to allow users
|
||
|
|
to have a standard customization file, which gets run when a program
|
||
|
|
requests it. This module implements such a mechanism. A program
|
||
|
|
that wishes to use the mechanism must execute the statement
|
||
|
|
|
||
|
|
import user
|
||
|
|
|
||
|
|
The user module looks for a file .pythonrc.py in the user's home
|
||
|
|
directory and if it can be opened, execfile()s it in its own global
|
||
|
|
namespace. Errors during this phase are not caught; that's up to the
|
||
|
|
program that imports the user module, if it wishes.
|
||
|
|
|
||
|
|
The user's .pythonrc.py could conceivably test for sys.version if it
|
||
|
|
wishes to do different things depending on the Python version.
|
||
|
|

||
