can I inherit *everything* from pandas (methods, functions, read_csv, etc etc etc etc)

Question

suppose I create a class with my own custom functions. I also want this class to inherit everything from Pandas.

class customClass(pandas.Dataframe):
    def my_func(x,y):
        return x+y.

instantiating

a = customClass()

typing "a." + tab I see I get a lot of pandas methods. but I'm missing somet other things like read_csv. is there a way to get that also? the objective would to just use this custom class for everything.

Answer 1

See the Python tutorial

The most important thing to notice for your specific question is that read_csv is not a method of DataFrame . When you use that method, you call

pd.read_csv("local_file.csv")

not

my_df.read_csv("local_file.csv")

Your customClass does not include that method; it's not reasonable to supposed that your custom instance would show that as a method choice.

For your use case, you would still use pandas.read_csv in building a data frame of your custom class.

If you want to inherit the entire pandas pantheon, then you'll need to do so explicitly. I don't recommend it.
