Python: Methods inside a method in a class

import numpy as np

class Y:
    def __init__(self):
        return None

    def f(self,x):
        return x

    def g(self,x):
        return f(x)**2
y=Y()
print y.g(3)

I know the above code will give error, but somehow I want to do the following, is there a modification to do?

Yup. It just takes a simple change. Since f(x) is a method, you need to call it on some object. What you want here is to call it on yourself, so very simply that line becomes:

return self.f(x)**2

The only reason it doesn't work is because you have f(x)**2 instead of self.f(x)**2. Make that change and it'll work perfectly.
