What about:
class MyClass:
hugeDict = loadHugeDic("filename.xml")
def __init__(self):
"""hugeDict can be accessed by self.hugeDict"""
...
The function loadHugeDict() will only be called once, when importing the
module for the first time. If you wanted to load it on the first
*instantiation*, you could do:
class MyClass:
hugeDict = None
def __init__(self):
if MyClass.hugeDict is None:
MyClass.hugeDict = loadHugeDic("filename.xml")
...
HTH.
