试图通过循环的Python函数传递多个值

问题描述：

我写了一个函数（或试图）从社交媒体服务获取统计信息，称为Crowd Tangle，并打印出前五个帖子的统计信息。我想弄清楚如何使用循环来传递函数中的值0到4来调用正确的JSON节点。我正在使用Python 3.6和Spyder。而不是复制函数五次，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。试图通过循环的Python函数传递多个值

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()

答

您可以将参数n_records添加到您的函数来表示数量的JSON记录要打印。然后在你的功能，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...

然后你就可以输入一个数字来表示你要多少条记录，当你调用该函数来打印，即：

get_crowdtangle_stuff(5)

那完美。谢谢！ – Eric
