我有一组名字,姓氏是大写的,中间名和中间名是正常的,例如。

OBAMA Barack
DEL MONTE Alfredo

我想在

中拆分它们
"OBAMA", "Barack"
"DEL MONTE", "Alfredo"

达到此目的的pythonic方式是什么?

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

打印:

OBAMA
Barack

DEL MONTE
Alfredo

您可以使用简单的正则表达式:

import re

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

或循环通过单词列表并过滤掉全大写的单词:

first = ' '.join(w for w in a.split() if w.isupper())
last =  ' '.join(w for w in a.split() if not w.isupper())

在我个人看来,“最pythonic”===“最简单”。

试试这个:

(?![A-Z][a-z])([A-Z ]+) ([A-Z][a-z]+)
