python腳本中使用in與not in用法 多個 組合 集合 or 或者 and

具體看樣例，更容易理解

#!/usr/bin/python
# -*- coding: utf-8 -*-

list_01 = ['A', 'B', 'C', 'H']
list_02 = ['A', 'B', 'E', 'F']

for letter in list_01:
    if letter in list_02:
        print(letter + ' is exists')
    else:
        print(letter + ' is not exists')

輸出結果如下：

A is exists
B is exists
C is not exists
H is not exists
