python: NameError：global name '…‘ is not defined

Question

in my code, I have:

class A:
    def a():
        ......

    def b():
        a()
        ......
    b()

Then the compiler will say “NameError: global name a() is not defined.” If I pull all the stuffs out of the class A, it would be no problem, but how can I define the method in class A? Thank you very much.

Answer 1

You need to call self.a() to invoke a from b. a is not a global function, it is a method on the class.

You may want to read through the Python tutorial on classes some more to get the finer details down.
