在python中,如何从多个列表中的单词创建和数组,单词出现次数[重复]

这个问题已经有了答案:

Count Words in Python 2答

我有一个json文件,它有多个带有文本字段的对象:

{
"messages": 
[
    {"timestamp": "123456789", "timestampIso": "2019-06-26 09:51:00", "agentId": "2001-100001", "skillId": "2001-20000", "agentText": "That customer was great"},
    {"timestamp": "123456789", "timestampIso": "2019-06-26 09:55:00", "agentId": "2001-100001", "skillId": "2001-20001", "agentText": "That customer was stupid\nI hope they don't phone back"},
    {"timestamp": "123456789", "timestampIso": "2019-06-26 09:57:00", "agentId": "2001-100001", "skillId": "2001-20002", "agentText": "Line number 3"},
    {"timestamp": "123456789", "timestampIso": "2019-06-26 09:59:00", "agentId": "2001-100001", "skillId": "2001-20003", "agentText": ""}
]
}

我只对“agentext”字段感兴趣。

我基本上需要去掉agentText字段中的每个单词,并对单词的出现次数进行计数。

所以我的python代码:

import json

with open('20190626-101200-text-messages.json') as f:
  data = json.load(f)

for message in data['messages']:
    splittext= message['agentText'].strip().replace('\n',' ').replace('\r',' ')
    if len(splittext)>0:
        splittext2 = splittext.split(' ')
        print(splittext2)

给我这个:

['That', 'customer', 'was', 'great']
['That', 'customer', 'was', 'stupid', 'I', 'hope', 'they', "don't", 'phone', 'back']
['Line', 'number', '3']

如何将每个单词添加到计数数组中? 如此喜欢;

That 2
customer 2
was 2
great 1
..

等等?

看看这个。

data = {
    "messages": 
        [
            {"timestamp": "123456789", "timestampIso": "2019-06-26 09:51:00", "agentId": "2001-100001", "skillId": "2001-20000", "agentText": "That customer was great"},
            {"timestamp": "123456789", "timestampIso": "2019-06-26 09:55:00", "agentId": "2001-100001", "skillId": "2001-20001", "agentText": "That customer was stupid\nI hope they don't phone back"},
            {"timestamp": "123456789", "timestampIso": "2019-06-26 09:57:00", "agentId": "2001-100001", "skillId": "2001-20002", "agentText": "Line number 3"},
            {"timestamp": "123456789", "timestampIso": "2019-06-26 09:59:00", "agentId": "2001-100001", "skillId": "2001-20003", "agentText": ""}
        ]
}

var = []

for row in data['messages']:
    new_row = row['agentText'].split()
    if new_row:
        var.append(new_row)

temp = dict()

for e in var:
    for j in e:
        if j in temp:
            temp[j] = temp[j] + 1
        else:
            temp[j] = 1

for key, value in temp.items():
    print(f'{key}: {value}')
