Do they know a tuple/list/dict when they see it?

Submitted by: Administrator
Dictionaries are consisting of pair of keys and values.like {'key':'value'}.

book={'cprog':'1024','c++':'4512'}

Keys are unique but values can be same. The main difference between list and tuple is you can change the list but you cannot change the tuple. Tuple can be used as keys in mapping where list is not.
