我有一个股票市场消息的api调用，应该会返回过去7天内的消息。我试图打印所有的数据，但当我运行程序时，它什么都不显示。只是空白。如何循环遍历所有值并打印对象中的所有数据？以下是回应。我需要打印日期、文本、情绪和股票行情。感谢的帮助

这是我的代码
from newsapi import NewsApiClient
import requests
import json
# Init
import winsound
import sqlite3
duration = 1000 # milliseconds
freq = 440 # Hz
response = requests.get("https://stocknewsapi.com/api/v1?tickers=AAPL,SQ,PLTR&items=50&date=last7days&token=myapikey")
def jprint(obj):
# create a formatted string of the Python JSON object
text = json.dumps(obj, sort_keys=True, indent=4)
print(text +' ff /n')
for i in response:
jprint(response.json()['data'][i]['date'] + ' title : ' + response.json()['data'][i]['title'] + " news " + response.json()['data'][i]['text'] + " sentiment " + response.json()['data'][i]['sentiment'] )
您不想在数据中循环吗？data是一个列表，response是一个字典，它有一个关键字，data。
for i in response['data'] :
...
根据您的代码，您应该从更新循环
for i in response:
至
for i in range( len( response.json()['data'] )):
并且您的代码将按原样工作(调整缩进后(
from newsapi import NewsApiClient
import requests
import json
# Init
import winsound
import sqlite3
duration = 1000 # milliseconds
freq = 440 # Hz
response = requests.get("https://stocknewsapi.com/api/v1?tickers=AAPL,SQ,PLTR&items=50&date=last7days&token=myapikey")
def jprint(obj):
# create a formatted string of the Python JSON object
text = json.dumps(obj, sort_keys=True, indent=4)
print(text +' ff /n')
for i in range( len( response.json()['data'] )):
jprint(response.json()['data'][i]['date'] + ' title : ' + response.json()['data'][i]['title'] + " news " + response.json()['data'][i]['text'] + " sentiment " + response.json()['data'][i]['sentiment'] )
但是你可以通过让生活变得更轻松
my_data=response.json()['data']
for i in range( len( my_data )):
jprint(my_data[i]['date'] + ' title : ' +my_data[i]['title'] + " news " + my_data[i]['text'] + " sentiment " + my_data[i]['sentiment'] )
基于json的数据和代码示例
import json
def jprint(obj):
# create a formatted string of the Python JSON object
text = json.dumps(obj, sort_keys=True, indent=4)
print(text +' ff /n')
