Question

['2006/10/18 21:15:51 4.823 -82.592 37.3 SOUTH OF PANAMA']  
['2006/10/18 10:08:45 32.165 -115.891 7.3 BAJA CALIFORNIA, MEXICO']

同一原始列表中有两个列表：

a = [['2006/10/18 21:15:51 4.823 -82.592 37.3 SOUTH OF PANAMA'], 
['2006/10/18 10:08:45 32.165 -115.891 7.3 BAJA CALIFORNIA, MEXICO'] ]

在这里，我想在国家/地区名称之前拆分它们，例如：

['2006/10/18 21:15:51 4.823 -82.592 37.3]' '[SOUTH OF PANAMA']  
['2006/10/18 10:08:45 32.165 -115.891 7.3]' '[BAJA CALIFORNIA, MEXICO']

我的问题是如何使用split（）（或者其他一些方法）让python理解我想在这个特定位置分离这些列表？

Answer 1

您可以使用ALTER TABLE users_users ADD FULLTEXT(firstname, lastname, link); $searchTerm = '+'.str_replace(' ','+',$search).'*'; $query = "SELECT * FROM users where MATCH(`firstname`,`lastname`,`link`) AGAINST (".searchTerm." IN BOOLEAN MODE)";：

re.split

输出：

import re
s = [['2006/10/18 21:15:51 4.823 -82.592 37.3 SOUTH OF PANAMA']  , ['2006/10/18 10:08:45 32.165 -115.891 7.3 BAJA CALIFORNIA, MEXICO']]
new_s = [re.split('(?<=\d)\s(?=[A-Z])', i) for [i] in s]

Answer 2

a = [['2006/10/18 21:15:51 4.823 -82.592 37.3 SOUTH OF PANAMA'], 
['2006/10/18 10:08:45 32.165 -115.891 7.3 BAJA CALIFORNIA, MEXICO'] ]

fixed_split = 5
b = [[' '.join(i[0].split()[:fixed_split]), ' '.join(i[0].split()[fixed_split:])] for i in a]
print(b)

输出

[['2006/10/18 21:15:51 4.823 -82.592 37.3', 'SOUTH OF PANAMA'], ['2006/10/18 10:08:45 32.165 -115.891 7.3', 'BAJA CALIFORNIA, MEXICO']]

Answer 3

re.split()是复杂分割的不错选择：

import re

[re.split('([\d\/\.\-\:\s]+)\s+([A-Z\s\,]+)', x[0])[1:3] for x in a]

在python3中，如何在特定位置拆分列表列表？
