Question on importing and function defs

[TC]

I have a problem. Here's a simplified version of what I'm doing:

I have functions a() and b() in a module called 'mod'. b() calls a().

So now, I have this program:

from mod import *

def a():
blahblah

b()
The problem being, b() is calling the a() that's in mod, not the new
a() that I want to replace it. (Both a()'s have identical function
headers, in case that matters.) How can I fix this?

Thanks for any help.

The only problem I could see with this is a local function issue.
Meaning that even when you write the new a() function in the main source
file, b() doesn't know it exists because it's relying on it's own
"local" a() in the module. I'm also new to using Python so I that's all
I can think would be the problem.

Since b calls mod.a, you could replace mod.a with your new a. Like
this: (Warning, this could be considered bad style because it will
confuse anyone who examines the mod module in an attempt to understand
you code.)
import mod

def replacement_a():
...

mod.a = replacement_a

...
Or another option. Define b to take, as a parameter, the "a" function
to call.

In mod:

def a():
...

def b(fn=a): # to set the default a to call
...

And you main program:

from mod import *

def my_a():
...

b(my_a)
Hope that helps
