Python 2 __getattr__ Max Recursion Depth

for example i use this code: class A(object): def __init__(self): self.dict1 = { 'A': 3, 'B': self.A} def __getattr__(self, key): if

Solution 1:

The reference to self.dict1 inside your __getattr__ method causes __getattr__ to be called again, and so on, hence the infinite recursion. The only safe way to access attributes of self inside __getattr__ is by using references to self.__dict__. Try

def __getattr__(self, key):
    if key in self.__dict__['dict1']:
        return self.__dict__['dict1'][key]

Note also that the absence of an else clause will mean undefined attributes appear to have the value None.
