eval() and global variables

[Juan Pablo Romero Méndez]

Hello,

Suppose this function is given:

def f(x,y):
  return x+y+k


Is it possible to somehow assign a value to k without resorting to
making k global?

I'm thinking something like this:

eval("f(1,1)", {"f":f, "k":1})

Or even better, something like:

def g(k):
  return f

g(1)(1,1) ==> 3


Regards,
