如何在Python中将数字字符串范围转换为列表 [英] How to convert numeric string ranges to a list in Python

问题描述

我希望能够将诸如"1,2,5-7,10"之类的字符串转换为诸如[1,2,5,6,7,10]之类的python列表.我环顾四周，发现了此，但是我想知道是否有一种干净简单的方法可以在Python中做到这一点.

I would like to be able to convert a string such as "1,2,5-7,10" to a python list such as [1,2,5,6,7,10]. I looked around and found this, but I was wondering if there is a clean and simple way to do this in Python.

推荐答案

def f(x):
    result = []
    for part in x.split(','):
        if '-' in part:
            a, b = part.split('-')
            a, b = int(a), int(b)
            result.extend(range(a, b + 1))
        else:
            a = int(part)
            result.append(a)
    return result

>>> f('1,2,5-7,10')
[1, 2, 5, 6, 7, 10]
