address this issue by adding doc strings. Nonetheless adding doc strings is a
good habit to get in to.

That's not an anonymous function then, is it? You want to assign a name
to that function, and (to be useful in development tools, such as a

Whey you need a simple function in Python, there is a choice between a
normal function declaration and an assignment of a anonymous function
(defined by a lambda-expression) to a variable:
def f(x): return x*x
or
f = lambda x: x*x
