Question

I have this noob error,

   l = instanciaHagale.multiplicaMethod() AttributeError: Hagale instance has no attribute 'multiplicaMethod'

here my code:

class Hagale :
    def __init__(self, a):
        self.a = a 
        print self.a 

        self.sumaleAlgo = self.a+34543 #variable creada on the fly!

        def multiplicaMethod (self):

            return 'self.cuadradoReal'
            #self.cuadradoReal = self.a * 2

instanciaHagale = Hagale(345)

print instanciaHagale.sumaleAlgo #acceso a las variables de mi objeto! 

l = instanciaHagale.multiplicaMethod()

print l 

Answer 1

    def __init__(self, a):
        # ...

        def multiplicaMethod (self):

The last def is indented wrong. Outdent it so it is at the same level as def __init__(self, a):, like this:

class Hagale(object):
    def __init__(self, a):
        self.a = a 
        print self.a 
        self.sumaleAlgo = self.a+34543 #variable creada on the fly!

    def multiplicaMethod (self): # <-- moved to the left
        return 'self.cuadradoReal'

Also note that your code uses classic classes. That’s probably not want you want, but it’s an easy fix – simply inherit from object.
