Python - 將兩個列表組合成一個json對象

Question

我有一個Python執行器，它解決了2個函數，即get_tech_courses()和get_music_courses()返回單個列表; 1和2。

清單1.

[ 
{'title': 'THE COMPLETE PYTHON WEB COURSE', 'downloads': '4', 'views': '88'}, 
{'title': 'THE COMPLETE JAVA WEB COURSE', 'downloads': '16', 'views': '156'} 
] 

清單2.

[ 
{'title': 'THE COMPLETE GUITAR COURSE', 'downloads': '18', 'views': '125'}, 
{'title': 'THE COMPLETE KEYBOARD COURSE', 'downloads': '63', 'views': '98'} 
] 

我想無論是列出了一個JSON數組父，courses這樣的捆綁下的結合：

{"courses": 
[{'title': 'THE COMPLETE PYTHON WEB COURSE', 'downloads': '4', 'views': '88'}, 

{'title': 'THE COMPLETE JAVA WEB COURSE', 'downloads': '16', 'views': '156'}, 

{'title': 'THE COMPLETE GUITAR COURSE', 'downloads': '18', 'views': '125'}, 

{'title': 'THE COMPLETE KEYBOARD COURSE', 'downloads': '63', 'views': '98'}] 
} 

這不是打印正確的json。

from concurrent.futures import ThreadPoolExecutor 

import tech_course 
import music_course 
import json 

courses = [] 

with ThreadPoolExecutor(max_workers=2) as executor: 
    courses.append(executor.submit(tech_course.get_tech_course).result()) 
    courses.append(executor.submit(music_course.get_music_course).result()) 

print(json.dumps(courses)) 

Answer 1

嘗試以下操作：

import json 

list_1 = [ 
    {'title': 'THE COMPLETE PYTHON WEB COURSE', 'downloads': '4', 'views': '88'}, 
    {'title': 'THE COMPLETE JAVA WEB COURSE', 'downloads': '16', 'views': '156'}] 

list_2 = [ 
    {'title': 'THE COMPLETE GUITAR COURSE', 'downloads': '18', 'views': '125'}, 
    {'title': 'THE COMPLETE KEYBOARD COURSE', 'downloads': '63', 'views': '98'}] 

res_dict = {"courses": list_1 + list_2 } 

to_json = json.dumps(res_dict) 

輸出：

>>> to_json 
'{"courses": [{"downloads": "4", "views": "88", "title": "THE COMPLETE PYTHON WEB COURSE"}, {"downloads": "16", "views": "156", "title": "THE COMPLETE JAVA WEB COURSE"}, {"downloads": "18", "views": "125", "title": "THE COMPLETE GUITAR COURSE"}, {"downloads": "63", "views": "98", "title": "THE COMPLETE KEYBOARD COURSE"}]}'
