Question

有没有办法替换字典中的特定值？我正在尝试用乌龟等其他东西代替喵。

meow只是字典中的一个值，但是我可能没有附加特定的键。

我尝试了这段代码，但无法正常工作，有没有办法不用json.dumps来做到这一点？

output_json = json.dumps(dict).replace('meow', 'turtle')

这是下面的json：

dict = {

是否有更好的方法来执行此操作，方法是在dict中搜索特定值并用乌龟替换喵，而无需进行任何unicode更改等。

Answer 1

是的，您可以做一个简单的for循环，这是简单字典的示例：

for i in dictionary:
    if dictionary[i]=='meow':
        dictionary[i]='turtle'

使用字典，您将获得每个字典键。您可以使用这些键查看值。

如果与另一个值匹配则替换特定的值
