Question

我写了一个函数（或者我试图）从名为Crowd Tangle的社交媒体服务获取统计数据，并打印出前五个帖子的统计数据。我试图弄清楚如何使用循环传递函数中的值0到4来调用正确的JSON节点。我使用的是Python 3.6和Spyder。而不是复制函数五次并写入0,1,2,3,4，有没有办法使用循环来做到这一点？任何建议或链接都会很棒。谢谢。

import requests 

def get_crowdtangle_stuff():
    url = 'https://api.crowdtangle.com/posts?token=mytoken'
    json_data = requests.get(url).json()
    #print(json_data)

    Platform = json_data['result']['posts'][0]['platform']
    Platform_string = str(Platform)
    print('This stupid thing was on the ' + Platform_string + '.')

    Title = json_data['result']['posts'][0]['message']
    Title_string = str(Title)
    print('This stupid thing was on the ' + Title_string + '.')

    Date = json_data['result']['posts'][0]['date']
    Date_string = str(Date)
    print('This stupid thing was posted on ' + Date_string)

    Like_count = json_data['result']['posts'][0]['statistics']['actual']
    ['likeCount']
    Like_count_string = str(Like_count)
    print('This stupid thing got ' + Like_count_string + ' likes.')

    Shares = json_data['result']['posts'][0]['statistics']['actual']
    ['shareCount']
    Shares_string = str(Shares)
    print('This stupid thing got ' + Shares_string + ' shares.')

    Comments = json_data['result']['posts'][0]['statistics']['actual']
    ['commentCount']
    Comments_string = str(Comments)
    print('This stupid thing got ' + Comments_string + ' comments.')

    Wow_count = json_data['result']['posts'][0]['statistics']['actual']
    ['wowCount']
    Wow_count_string = str(Wow_count)
    print('This stupid thing got ' + Wow_count_string + ' wows.')

    Total_engagement = Like_count + Shares + Comments + Wow_count
    Total_engagement_string = str(Total_engagement)
    print('This stupid things total engagement score is ' + 
    Total_engagement_string + '.')

    Link = json_data['result']['posts'][0]['link']
    Link_string = str(Link)
    print('This stupid thing has a link of ' + Link_string + '.')

get_crowdtangle_stuff()

您可以在函数中添加参数n_records，以表示要打印的JSON记录数。然后在你的函数中你可以创建一个循环：

for n in range(n_records):
    ...Rest of your code here where you can use n to retrieve the JSON record and print the outputs your want...

然后，您可以输入一个数字来表示调用该函数时要打印的记录数，即：

get_crowdtangle_stuff(5)

尝试通过带循环的Python函数传递多个值
