我想根据得分对字典进行排序。 如果得分相同, 则按名称排序

{ 
 sudha   : {score : 75} 
 Amruta  : {score : 95} 
 Ramesh  : {score : 56} 
 Shashi  : {score : 78} 
 Manoj   : {score : 69} 
 Resham   : {score : 95} 
} 

Help plz Thanks.

最佳回答

我觉得这应该有用...

sorted(yourdict,key=lambda x:(yourdict[x][ score ],x))

它通过比较图例( score, name) 有效 。 图例比较查看第一个项目 -- -- 如果它们相同, 它查看第二个项目等等 。 所以, (55, j) & gt; (54, 柠檬) 和 (55, j) & lt; (55, k) 。

当然,这返回了 yourdict 的密钥,按所要的顺序排列 -- -- 无法对字典进行实际排序,因为字典没有顺序概念。

问题回答
d = { 
 sudha   : { score  : 75},
 Amruta  : { score  : 95},
 Ramesh  : { score  : 56}, 
 Shashi  : { score  : 78}, 
 Manoj   : { score  : 69}, 
 Resham   : { score  : 95}, 
} 

sorted(d, key=lambda x: (d[x][ score ], x))

返回:

[ Ramesh ,  Manoj ,  sudha ,  Shashi ,  Amruta ,  Resham ]
