Python operators - frequently used member operators (example analysis)

In today’s article, we will talk about the member operators among Python operators. I hope this article can help you reading.

Member operators:

In addition to some of the operators mentioned before, Python also supports member operators. The test example contains a series of Members, including strings, lists or tuples, as shown below:

The following examples demonstrate the operation of all Python member operators:

#!/usr/bin/python
# -*- coding: UTF-8 -*-
 
a = 10
b = 20
list = [1, 2, 3, 4, 5 ];
 
if ( a in list ):
   print "1 - 变量 a 在给定的列表中 list 中"
else:
   print "1 - 变量 a 不在给定的列表中 list 中"
 
if ( b not in list ):
   print "2 - 变量 b 不在给定的列表中 list 中"
else:
   print "2 - 变量 b 在给定的列表中 list 中"
 
# 修改变量 a 的值
a = 2
if ( a in list ):
   print "3 - 变量 a 在给定的列表中 list 中"
else:
   print "3 - 变量 a 不在给定的列表中 list 中"

The output result of the above example is as follows:

1 - 变量 a 不在给定的列表中 list 中
2 - 变量 b 不在给定的列表中 list 中
3 - 变量 a 在给定的列表中 list 中
