class my_class:
def __init__(self, attr1, attr2):
self.attr1 = attr1 #string
self.attr2 = attr2 #string
def __lt__(self, other):
if self.attr1 < other.attr1:
return True
else:
return self.attr2 < other.attr2
I will run into problems if attr1 or attr2 is None, and they
legitimately can be.
I know I can check for attr1 or attr2 or both being None and react
accordingly, but my real class has ten attributes and that approach
will be long. What are my alternatives?
