如何定义一个Python函数，对给到的一个set或list，如：
set(1, 2, 3, 5, 6, 7, 8)
进行操作，判断连续的数字范围并分块，再返回如下字符串：
"1-3, 5-8"
刚学习Python, 对这些算法的实现还是有点迷茫，老司机们有没有好办法？谢谢！
学习是最好的投资！
Group by value minus subscript
# coding: utf-8 from itertools import groupby lst = [1, 2, 3, 5, 6, 7, 8, 11, 12, 13] fun = lambda (i, v): v - i for k, g in groupby(enumerate(lst), fun): print [v for i, v in g] #由于python3中lambda不支持用括号的方式解压，只能这样写 fun = lambda x: x[1] - x[0]
