Python supports the creation ofanonymous functions(i.e. functions that are not bound to a name) at runtime, using a construct called lambda. This is not exactly the same as lambda in functional programming languages such as Lisp, but it is a very powerful concept that's well integrated int...
All of Python's immutable built-in objects are hashable, while no mutable containers (such as lists or dictionaries) are. Objects which are instances of user-defined classes are hashable by default; they all compare unequal, and their hash value is their id(). -from Python glossary Convert ...
