I have a method (__init__) in a class, and I want to use a function from the class in this method.
But when I want to run my program. I get: NameError: global name 'myfunction' is not defined
Someone, who knows what I have to do? :)
Thank you. But I have still a problem, because def myFunc(self, a): is a method and I wanted a function.
class Myclass(object):
def __init__(self, a):
self.a = self.myFunc(a)
def myFunc(self, a):
return a+1
Then you don't have a function call in the method, but you have a method call in it. When creating a class you must specify the object when calling its methods:
>>> class A(object):
... def __init__(self, val):
... self.val = self._process(val)
... def _process(self, val):
... return val % 7
... process = _process #if you are outside methods then you don't
... #have to add "self.".
...
>>> a = A(5)
>>> a.process(3)
3
>>> a._process(6) #"a" is passed as the "self" parameter
6
As you can see in a class definition, but outside the methods you must specify the method name only, and not the "self.". Also you can't refer to a method not already defined:
>>> class B(object):
... def __init__(self):pass
... def method1(self):pass
... __call__ = method2 #method2 not defined!
...
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 4, in B
NameError: name 'method2' is not defined
self? So the call should beself.myfunction().
