JSON Python的讀取/寫入到一個JSON文件問題

Question

代碼：

import json 

numbers = [2, 3, 5, 7, 11, 13] 
letters = ["a", "b", "c", "d"] 
filename = 'numbers.json' 

with open(filename, 'w') as f_obj: 
    json.dump(numbers, f_obj) 
    json.dump(letters, f_obj) 


with open(filename) as f_obj: 
    numbers = json.load(f_obj) 
    letters = json.load(f_obj) 

print(numbers) 
print(letters) 

我希望能夠讀取我已經加入到一個JSON文件多個列表，並將它們設置爲可以使用單獨的列表後來。

我不介意在json文件中的每個列表之間添加一個新行，然後以行格式讀取它。

爲什麼不把它們存儲在全局字典中？

import json 

numbers = [2, 3, 5, 7, 11, 13] 
letters = ["a", "b", "c", "d"] 
filename = 'numbers.json' 

val={'numbers': numbers, 'letters':letters} 

with open(filename, 'w') as f_obj: 
    json.dump(val, f_obj) 


with open(filename) as f_obj: 
    val = json.load(f_obj) 
    numbers = val['numbers'] 
    letters = val['letters'] 

print(numbers) 
print(letters)
