Where on earth did you get that from? I presume you mean "You can't use 
a def statement as an argument to a function"?

There is nothing wrong with

   def adder(x):
     def func(y):
         return x+y
     return func

for example. Then adder(5) returns a function that returns 5 more than 
its argument.
