monkey patch without the need to intitalise
Patching an existing class, e.g. pd.DataFrame, so that all instances have a patched method is not trivial, IMO.
What about simply subclassing pd.DataFrame?
import pandas as pd


class MyDataFrame(pd.DataFrame):
    def my_func(self):
        print("yey")

df = MyDataFrame()
df.my_func()

# Outputs:
# yey


I would like to money patch a function without the requirement to initialize using pd.DataFrame.function = function
For example, if I have a dataframe df and I call df.unique() I do not have to run pd.DataFrame.unique = unique prior to running as this appears to be built in. Is there a way I can do the same for my own functions without the need to initialise every time?
