Python常见问题
我有一个结构非常复杂的大JSON文件
您可以在这里查看：https://drive.google.com/file/d/1tBVJ2xYSCpTTUGPJegvAz2ZXbeN0bteX/view?usp=sharing
它包含700多万行，我只想提取“text”字段
我已经编写了一个python代码，在整个文件中增加了“text”键或字段的所有值，它只提取了12个值！当我在Visualstudio上打开JSON文件时，我有超过19000个值
您可以在此处看到代码：
import json
import csv
with open("/Users/zahraa-maher/rasa-init-demo/venv/Tickie/external_data/frames2.json") as file:
data = json.load(file)
fname = "outputText8.csv"
with open(fname, "w") as file:
csv_file = csv.writer(file,lineterminator='\n')
csv_file.writerow(["text"])
for item in data[i]["turns"]:
csv_file.writerow([item['text']])
请看一看JSON文件，因为它非常大，结构复杂，所以我不会将它粘贴到这里查看，因为它不可理解
这也是son文件的一部分：
