Define a dictionary:　　　　among them: 1. The same key is not allowed to appear two times. When created, if the same key is assigned a value of two times, the latter value is remembered. 2. The key must be immutable, so it can be used as a number, string, or tuple, but not with a listCommon operations for dictionaries:1. Adding, deleting, changing and checking:　　　　　　　2.type, Len, str usage:3. Return of the list:　　　　　　　　4.
