How to save a dictionary and a list in the same json file with python?-CodePudding

I wish to save a dictionary and a list in one json file so that when I parse the file I could distinguish them. This is the function I use to save the dictionary in the json file:

def save_callback():
    #folder = filedialog.askdirectory()
    file = filedialog.asksaveasfilename()
    with open(file,'w') as file:
        file.write(json.dumps(test_dict))
    os.rename(file.name,file.name   ".txt")

What should I add to this function to save the list too?

CodePudding user response：

Since JSON objects can be arbitrarily nested, the easiest solution is to store both the dict and the list inside another object:

data = json.dumps([test_dict, test_list])

Then you can load it like this:

test_dict, test_list = json.loads(data)
