what is the difference for python between lambda and regular function?

Question

I\'m curious about the difference between lambda function and a regular function (defined with def) - in the python level. (I know what is the diff

Answer 1

The only difference is that (a) the body of a lambda can consist of only a single expression, the result of which is returned from the function created and (b) a lambda expression is an expression which evaluates to a function object, while a def statement has no value, and creates a function object and binds it to a name.

In all other material respects they result in identical objects - the same scope and capture rules apply. (Immaterial differences are that lambda-created functions have a default func_name of "". This may affect operation in esoteric cases - e.g. attempts to pickle functions.).
