在python2中的range

[root@python01 scripts]# cat sum100.py 
#/usr/bin/python
# -*- coding:UTF-8 -*-
number = range(1,101)
print(number)
[root@python01 scripts]# python sum100.py 
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100]

在python3中的range

[root@python01 scripts]# cat sum100.py
#/usr/bin/python3
# -*- coding:UTF-8 -*-
number = range(1,101)
print(number)
[root@python01 scripts]# python3 sum100.py
range(1, 101)

在python2中range返回的是一个可迭代的数组，python3中返回的是一个对象，因此python2可求1到100总和，如下

[root@python01 scripts]# cat sum100.py 
#/usr/bin/python
# -*- coding:UTF-8 -*-
number = range(1,101)
value = sum(number)
print(value)
