Where can I get the module MyUtils?

[Python_Doctor]

I inherited a piece of python code which imports "MyUtils" i.e. it has
a line:

import MyUtils

When I execute the code I get:

ImportError: No module named MyUtils

I assume the code is looking for another module called MyUtils.py. Is
this a standard Python module? Where can I download this module from?

Many thanks
