将 dict (of list) 写入 file.txt

Question

我坚持将列表的字典写入 .txt 文件。

我有一个这样的 lict 字典：

product_menu_list = {"Shirt": ["Red", "Orange", "Purple"], "Dress": ["Blue", "Yellow", "Green"]}

要将其写入 .txt 文件，我写道：

product_lines = product_menu_list
with open('product_record.txt', 'w') as f:
    for line in product_lines:
        f.write(json.dumps(product_lines))
        f.write('\n')

通过编写上面的代码，我可以得到：

{"Shirt": ["Red", "Orange", "Purple"], "Dress": ["Blue", "Yellow", "Green"]}

那不是我想要的格式。

但是，我想要的是在 .txt 文件中逐行编写，例如：

Shirt:
    Red
    Orange
    Purple

Dress:
    Blue
    Yellow
    Green

我怎样才能达到预期的输出？

尝试：

product_lines = product_menu_list
with open('product_record.txt', 'w') as f:
    for line in product_lines:
        f.write(json.dumps(line))
        f.write('
')
