用大写字母拆分一串单词

Question

我有一组名字，姓是大写的，名字和中间名是正常的，例如

OBAMA Barack
DEL MONTE Alfredo

我想把这些分开

^{pr2}$

Python的方法是什么？在

Answer 1

def split_names(names):
    for s in names:
        last_names = []
        name_parts = s.split()
        while name_parts and name_parts[0].isupper():
            last_names.append(name_parts.pop(0))
        yield ' '.join(last_names), ' '.join(name_parts)


names = ["OBAMA Barack", "DEL MONTE Alfredo"]
for last_name, first_name in split_names(names):
    print last_name
    print first_name
    print

印刷品：

^{pr2}$

Answer 2

>>> import itertools
>>> [
...    ' '.join(items)
...    for _, items in itertools.groupby('DEL MONTE Alfredo'.split(), str.isupper)
... ]
['DEL MONTE', 'Alfredo']

Answer 3

可以使用一个简单的正则表达式：

import re

a = "DEL MONTE Alfredo"
first, last = re.match(r'([A-Z ]+)\s+(.+)', a).groups()

或者循环查看单词列表并过滤掉所有大写字母：

^{pr2}$

在我个人看来，“最棒的Python”===“最简单的”。在
