Thank you for your suggestion. I did not create the original script, so it
will stay as is and my addition for the menu has been adjusted.
Now that I can make a clear distinction of what I am returning, I am getting a
new error that leads me that I am trying to call a function that cannot be seen
when instantiated:
To add a name, please input he following information:
Name: Bryan
Number: 1234567890
What type of number is this? (choose one):
1. Home:
2. Work:
3. Cell:
: 1
Traceback (most recent call last):
File "menu_modified.py", line 95, in <module>
menu.addName()
File "menu_modified.py", line 73, in addName
enter(name, number, returnType)
AttributeError: phoneentry instance has no __call__ method
[code]
class MenuInput:
# ask user to input data and store to be passed to manageable variables.
def addName(self):
print "To add a name, please input he following information: "
name = raw_input("Name: ")
number = raw_input("Number: ")
get = int(raw_input("What type of number is this? (choose one):
\n \
1. Home:\n \
2. Work:\n \
3. Cell:\n \
: "))
returnType = self.numberType(get)
#print returnType
enter = phoneentry()
enter(name, number, returnType)
[/code]
I googled the __call__ method, but I am not getting to the meat of what all of
the leads have to say. I know it has to deal with when I instantiated
phoneentry() within addName(), I just don't know how to fix it or "call" it
properly.
Again, thanks in advance.

Bypassing the whole 'function within function' problem, consider
using a dictionary instead: somedict = {1: HOME, 2: WORK, 3: FAX},
and self.type = somedict[self.get]. This also avoids endless if-elif-
elif-elif sequences (looking at showtype() in your original script,
where you can
apply the same technique); it's often clearer, and
certainly shorter.
