No method overloading

[Hussein B]

Hey,
Please correct me if I'm wrong but Python doesn't support method
overload, right?
--
def method(self):
#code
def method(self, data):
#code
--
The last declaration of method() erase the previous one (like
JavaScript).
Thanks.

Correct. The second declaration overwrites the first. Give data a
default argument instead:
def method(self, data=None):
if data is None:
# Normal code
else:
# data included code

Not sure how Pythonic that is, but it should work the way you're
requesting... I think.

in Python, methods are callable attributes, and an attribute can only
have one value. you can use default arguments to work around this:

def method(self, data=None):
if data is None:
#code
else:
#code
