Tkinter menu question--how to pass arguments

I'm having difficulty structuring a Tkinter menu entry. Here is the 
command in question:

self.finkmenu.add_command(label='Update List of Packages', 
command=self.authorizeCommand(self.scanPackages))

When I start my program, it crashes because it's trying to run the 
command self.authorizeCommand. The reason I'm structuring it in this 
fashion is that this command takes another command as an argument--in 
this case, self.ScanPackages.

The basic structure of the program is that the self.authorizeCommand 
function pops up a dialog box for a password; it then feeds the password 
to the function that it takes as an argument, i.e. self.scanPackages.

I tried setting up the menu entry without the additional parameter, i.e. 
command=self.authorizeCommand, but then when I try to run the command 
from the menu, it complains there are not enough arguments. 
Unsurprising, since self.authorizeCommand takes another function name as 
an argument.

How can I structure the menu item to reflect the correct number of 
arguments without it trying to execute the command?
