python之获取字典值的 value_counts()

我很熟悉如何返回value_counts来自 pd.Series。但是，如何从字典的值中获取值计数？

假设我在字典 L 中有以下元组:

L = {1: (13600, 14797), 
     2: (14700, 14700), 
     3: (14700, 10400), 
     4: (14600, 17200), 
     5: (13600, 14797), 
     6: (14600, 17200), 
     7: (14700, 10400), 
     8: (14700, 10400), 
     9: (12800, 14770)} 

如何从 L 中获取 value_counts，如下所示:

(14700, 10400) 3 
(13600, 14797) 2 
(14600, 17200) 2 
(14700, 14700) 1 
(12800, 14770) 1 

这就是我目前所拥有的。但是，我认为字典键 1-9 妨碍了我，因为我收到错误 list object is not callable.

list = [(k, v) for k, v in L.items()]  
S = set(L) 
F = {} 
for i in list(S): 
    F[i] = list.count(i)
