Python Meta Dictionary

The Dictionary (dictionary) is the most flexible built-in data structure type in Python, except for lists. A list is an ordered combination of objects, and a dictionary is a collection of unordered objects.

The difference between the two is that the elements in the dictionary are accessed by keys, not by offsets.

The dictionary is identified with "{}". A dictionary consists of an index (key) and a value corresponding to it.

#!/usr/bin/python

#-*-Coding:utf-8-*-

Dict = {}

dict[' One ' = "This is one"

DICT[2] = "This is the"


tinydict = {' name ': ' John ', ' Code ': 6734, ' dept ': ' Sales '}

Print dict[' One ' # output key is ' one ' value

Print dict[2] # output key value of 2

Print Tinydict # Output a complete dictionary

Print Tinydict.keys () # Output all keys

Print tinydict.values () # Output all values

The output is:

This is one that is both {' dept ': ' Sales ', ' Code ': ' 6734, ' name ': ' John '} [' dept ', ' Code ', ' name '] [' Sales ', 6734, ' John ']
