#方法一：
a={
    
    }
for i in nums:
    a[i] = nums.count(i)
print(a)  

Resultado de salida:

{
    
    '219': 26, '222': 26, '224': 1, '226': 32}

#方法二：
my_dict = {
    
    }
for i in nums:
    if i in my_dict:
        my_dict[i] += 1
    else:
        my_dict[i] = 1
print(my_dict)

Resultado de salida:

{
    
    '219': 26, '222': 26, '224': 1, '226': 32}

#方法三：
from collections import Counter
a = Counter(nums)
print(dict(a))

Resultado de salida:

{
    
    '219': 26, '222': 26, '224': 1, '226': 32}
