What do you mean by class initialization? If you want to read the files
and populate the lists when the class is defined, it might work to do
this at the module level. Then the lists would be populated when the
module is first imported:
## mymodule.py
specialList = open('specialfile.txt').readlines() # Whatever file
processing you need goes here
class MyClass(object):
# etc
# do something with specialList
If you want to read the files when an instance is initialized, then put
the code in the class __init__() method.
