How to enter values ​​into dictionary in python

Python dictionary is another mutable container model and can store any type of object, such as strings, numbers, tuples and other container models.
1. Create a dictionary
A dictionary consists of pairs of keys and corresponding values. Dictionaries are also called associative arrays or hash tables. The basic syntax is as follows:

dict = {'Alice': '2341', 'Beth': '9102', 'Cecil': '3258'}

You can also create a dictionary like this

dict1 = { 'abc': 456 }
dict2 = { 'abc': 123, 98.6: 37 }

Note:
Each key and value are separated by a colon (:), each pair is separated by a comma, and each pair is separated by a comma. Split and place the whole in curly braces ({}).
Keys must be unique, but values ​​do not.
The value can be of any data type, but it must be immutable, such as string, number or tuple.

Modify the dictionary:
The way to add new content to the dictionary is to add new key/value pairs, modify or delete existing key/value pairs as follows:

dict = {'Name': 'Zara', 'Age': 7, 'Class': 'First'};

dict['Age'] = 8; # update existing entry
dict['School'] = "DPS School"; # Add new entry

 
print "dict['Age']: ", dict['Age'];
print "dict['School']: ", dict['School'];
#以上实例输出结果：
#dict['Age']:  8
#dict['School']:  DPS School
