如何通過API循環時遇到錯誤

Question

非常簡單的問題，我嘗試了多種方法來解決，但我認爲我傳遞了一些非常容易解決的問題。

import requests 

# Make an API call and store the response. 
url = 'https://api.github.com/search/repositories?q=language:python&sort=stars' 
r = requests.get(url) 
print("Status code:", r.status_code) 

# Store API response in a variable. 
response_dict = r.json() 
print("Total respositories:", response_dict['total_count']) 

# Explore information about the respositories. 
repo_dicts = response_dict['items'] 
print("Respositories returned:", len(repo_dicts)) 

print("\nSelected information about each respository:") 
for repo_dict in repo_dicts: 

    print('\nName:', repo_dict['name']) 
    print('Owner:', repo_dict['owner']['login']) 
    print('Stars:', repo_dict['stargazers_count']) 
    print('Respository:', repo_dict['html_url']) 
    print('Description:', repo_dict['description']) 

循環播放大多數加星項目的github api，並打印每個存儲庫的信息。其中一個存儲庫'沒有描述，所以我怎麼會跳過這個描述或說'沒有可用的描述'，而沒有我的程序崩潰。

謝謝。

Answer 1

這可能適合你。只是一個簡單的if語句來檢查一個空字符串。

for repo_dict in repo_dicts: 
    ... 
    if not repo_dict['description']: 
     print('No description') 
    else: 
     print('Description:', repo_dict['description']) 

Answer 2

這可能會爲你工作：

for repo_dict in repo_dicts: 

    print('\nName:', repo_dict.get('name', None)) 
    print('Owner:', repo_dict['owner'].get('login', None)) 
    print('Stars:', repo_dict.get('stargazers_count', None)) 
    print('Respository:', repo_dict.get('html_url', None)) 
    print('Description:', repo_dict.get('description', None)) 

返回None如果鍵的值是空的。
