Let's try this one more time. I thought that I would try to make Alan's
code work. Here is the version what I have now:
class Printer:
def __init__(self,number=0):
self.value = number
def sayIt(self):
print self.value
class MyApp:
def __init__(self, aPrinter = None):
if aPrinter == None: # if no object passed create one
aPrinter = Printer()
self.obj = aPrinter # assign object
def doIt():
self.obj.sayIt() # use object
def test():
p = Printer(42)
a1 = MyApp()
a2 = MyApp(p) # pass p object into a2
a1.doIt(self) # prints default value = 0
a2.doIt(self) # prints 42, the value of p
test()
When I run it, I get an error:
Traceback (most recent call last):
File "alan_class.py", line 22, in <module>
test()
File "alan_class.py", line 19, in test
a1.doIt(self) # prints default value = 0
NameError: global name 'self' is not defined
