How to extract the Max value within the same key

Question

{'201001': [36, 88, 65, 113, 51, 88, 37, 106, 96, 68, 104, 93],
 '201002': [65, 85, 97, 52],
 '201003': [85, 63, 86, 52, 71, 53, 51, 48, 52],
 '201004': [82, 39, 97, 114, 74, 30, 97],
 '201005': [97, 66, 109, 98, 94, 78, 99, 53, 67, 56],
 '201006': [116, 98, 39, 69, 33, 84, 62, 39],
 '201007': [72, 98, 37],
 '201008': [98, 31, 99, 105, 109, 72, 30, 34]}

I have a dictionary looks something like this, and I want to extract the maximum value within the same key. And create a new dictionary with only one max value per key. I have tried the solution provide by Tomerar. But encountered some error, shown below. Does anyone have any idea how to do this? Thanks.

After running the code from Tomerar

[input]

   for key,val in dict_all.items(): 
   print(type(val)) 

[output]

    list 

[input]

    dict_all  
    {key:max(val) for key,val in dict_all.items()} 

[output]

      1 dict_all 
----> 2 {key:max(val) for key,val in dict_all.items()}
      TypeError: '>' not supported between instances of 'str' and 'int' 

Answer 1

dict_t = {
    "201001":[1,2,3,4,5],
    "201002":[6,7,8,9,1],
    "201003":[8,9,10,12],
    "201004":[1,20,21,40,100],
}
{key:max(val) for key,val in dict_t.items()}
#output
{'201001': 5, '201002': 9, '201003': 12, '201004': 100}
