使用python对联系人列表排序并将输出存储在JSON中

我有一个联系人列表文件“input.txt”，我想按LastName和FirstName排序。该文件还具有最喜爱的颜色和邮政编码

该文件的内容结构如下：

LastName, FirstName, (123)-123-1234, Blue, 11013
FirstName LastName, Green, 12345, 123 123 1234
FirstName, LastName, 12345, 123 123 1234, Yellow

input.txt：

Annalee Loftis, green, 74339, 360 105 7811
Quinton, Liptak, 87225, 194 974 1020, yellow
Demming, Kent, (753)-851-4445, blue, 81403
Humperdink, Englebert G., (232)-955-1267, aqua marine, 28278
Corliss Nurse, green, 123123121, 640 163 2354

以下是我到目前为止在Python3中编写的代码

import os
import string
import re
f = open("input.txt", "r")
for i in f:
  if i and i[0].isalpha(): // proccess lines that starts with alphabet
    a = str((i.split(", ")))
    print(a)

现在，如何在JSON中按lastname、firstname和output排序

谢谢。

您可以为内置函数

sorted（）

编写自定义

键

函数。解析是通过

re

模块完成的

import re
from pprint import pprint

# the last and first name table:
# LastName, FirstName, (123)-123-1234, Blue, 11013
# FirstName LastName, Green, 12345, 123 123 1234
# FirstName, LastName, 12345, 123 123 1234, Yellow

data = """
Annalee Loftis, green, 74339, 360 105 7811
Quinton, Liptak, 87225, 194 974 1020, yellow
Demming, Kent, (753)-851-4445, blue, 81403
Humperdink, Englebert G., (232)-955-1267, aqua marine, 28278
Corliss Nurse, green, 123123121, 640 163 2354"""

g = re.findall(r'^(.*?), (.*?), (.*?), (.*?)$', data, flags=re.M)

def get_first_last(v):    
    if v[1].lower() == 'green':
        first_name, last_name = v[0].split()
    elif v[-1].lower() == 'yellow':
        first_name, last_name = v[0], v[1]
    else:
        first_name, last_name = v[1], v[0]

    return last_name, first_name

pprint(sorted(g, key=lambda v: get_first_last(v)))

这将打印：

[('Demming', 'Kent', '(753)-851-4445', 'blue, 81403'),
 ('Humperdink', 'Englebert G.', '(232)-955-1267', 'aqua marine, 28278'),
 ('Annalee Loftis', 'green', '74339', '360 105 7811'),
 ('Corliss Nurse', 'green', '123123121', '640 163 2354'),
 ('Quinton', 'Liptak', '87225', '194 974 1020, yellow')]

要将列表输出为Json，可以执行以下操作：

sorted_data = (sorted(g, key=lambda v: get_first_last(v)))
pprint(json.dumps(sorted_data, indent=4))

其中打印：

('[\n'
 '    [\n'
 '        "Demming",\n'
 '        "Kent",\n'
 '        "(753)-851-4445",\n'
 '        "blue, 81403"\n'
 '    ],\n'
 '    [\n'
 '        "Humperdink",\n'
 '        "Englebert G.",\n'
 '        "(232)-955-1267",\n'
 '        "aqua marine, 28278"\n'
 '    ],\n'

 '        "Annalee Loftis",\n'

 '    ],\n'
 '    [\n'
 '        "Corliss Nurse",\n'
 '        "green",\n'
 '        "123123121",\n'
 '        "640 163 2354"\n'
 '    ],\n'
 '    [\n'

 '    ]\n'
 ']')

您的代码甚至不能确定名称的不同部分在哪里。
