Question

我很抱歉提出这个问题，但我已经看了但是找不到答案。我老实说是新手。我正在尝试从json csv文件生成一个完整单词列表。我已经创建了一个行列表，但是我不能使用split（）来生成包含单独单词的新列表（稍后我需要计算单词出现次数）。我的输入文件包含twitter信息： twitter data 我试着写简单的代码：

myfile=open('fileName','r')
words=[]
for line in myfile:
    words.append(line.split())

len(words)=82

我也尝试过reader = csv.reader（myFile）和reader = csv.DictReader（myFile）

但总的来说我可以得到每一行，但是如何进一步将字符串/行拆分成独立的单词。对不起，谢谢你。

我的数据#I更改为另一个示例，因为最后一个可能格式不正确：

id,flags,expiration,cas,value

这不是最好的解决方案，只是来自菜鸟（我）的努力，肯定需要进一步编辑以获得更好的输出。我正在使用Windows操作系统。

import csv
import json
abc=[]
myList=[]
myDict={}
myFile=open('fileName.csv','r',encoding='utf-8')
myReader=csv.reader(myFile)
header=next(myReader)
for line in myReader:
     abc=json.loads(line[4])
     myDict=abc
     myList.append(myDict['text'])
dct={}
for eachLine in myList:
    item=eachLine.split()
    for one in item:
        if one in dct:
           dct[one]+=1
        else:
           dct[one]=1
finalList=list(dct.items())
finalList.sort()

使用python从json csv文件创建列表
