'Aggregaterating': '4.9', 'Ratingcolor': 'lightgreen', 'Ratingtext': 'Excellent'}}

我尝试使用以下代码进行排序：

sorted(frontend_content,key=lambda x:frontend_content[x]['name'])，但我没有零钱

我该如何根据一个特定的字段排序，比如姓名或投票

Answer 1

在python中不能对dict排序，因为它是无序的，所以需要首先将它转换为其他数据类型，如list of list或list of tuple

x = {6317637: {'name' : .... } }
sorted_x = sorted(x.items(),key = lambda kv : kv[1]['Votes'])

通过调用x.items()，您将它作为(key,value)的元组进行迭代。因此，kv[1]将是这里的值
