The super() __init__ function fills in the fields of a super object without checking if they were already set. If someone happens to call __init__ again, the previously-set references will end up getting forgotten and leak memory. For example: import sys print(sys.gettotalrefcount()) sp = super(int, 1) for i in range(100000): super.__init__(sp, float, 1.0) print(sys.gettotalrefcount()) |
