[issue42379] Optional List Args Persist Across Objects

[Eric V. Smith]

Eric V. Smith <eric at trueblade.com> added the comment:

This is defined behavior in the language, so it's not a bug. The "pythonic" way to deal with this is usually:

def funct(self, array = None):
    if array is None:
         array = []
