Incorrect use of super() in pandas core module #13482
Description
Existing Code
In the pandas core module base.py, the __sizeof__ member of the PandasObject class uses the following line:
return super(self, PandasObject).__sizeof__()
Expected Code
This is an incorrect use of super, which is supposed to have the type argument before the object argument (reference). This also results in a known problem with the memory tracking tool pympler (reference). The corrected line should instead be:
return super(PandasObject, self).__sizeof__()
output of pd.show_versions()
