Question

I have two files. In the first there is a dictionary ready for export:

__all__ = ['container']

def show_name(self):
   myFunction()
   print self.name

container = {
   'show_name': show_name
}

In the second file I import myFunction and I define the class Person:

from myModule import myFunction

class Person:
   def __init__(self):
      self.name = 'Bob'
      self.show_name = types.MethodType(container['show_name'], self)

person = Person()

The problem is that when I call person.show_name() I get the error:

NameError: global name ‘myFunction’ is not defined

How can I have Person.show_name access the same functions Person does?

Answer 1

Move from myModule import myFunction to the same file where show_name is defined.

By the way,

class Person:
   def __init__(self):
      self.name = 'Bob'
      self.show_name = types.MethodType(container['show_name'], self)

makes ('show_name',<bound_method>) a key-value pair in self.__dict__. That causes every instance of Person to get a new, independent key-value pair.

To save memory, you might want to change that to Roman Bodnarchuk other solution.

class Person:
   show_name = container['show_name']
   def __init__(self):
      self.name = 'Bob'
