初步认识Python中的列表与位运算符

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

list = [ 'abcd', 786 , 2.23, 'john', 70.2 ]
tinylist = [123, 'john']

print list # 输出完整列表
print list[0] # 输出列表的第一个元素
print list[1:3] # 输出第二个至第三个的元素 
print list[2:] # 输出从第三个开始至列表末尾的所有元素
print tinylist * 2 # 输出列表两次
print list + tinylist # 打印组合的列表

['abcd', 786, 2.23, 'john', 70.2]
abcd
[786, 2.23]
[2.23, 'john', 70.2]
[123, 'john', 123, 'john']
['abcd', 786, 2.23, 'john', 70.2, 123, 'john']

#!/usr/bin/python

Line 1 - Value of c is 12
Line 2 - Value of c is 61
Line 3 - Value of c is 49
Line 4 - Value of c is -61
Line 5 - Value of c is 240
Line 6 - Value of c is 15
