如何获取不同字典中相同键的所有值，并且字典存储在列表中

Question

from collections import defaultdict

some_dict = defaultdict(list)

index_dict = dict.fromkeys(range(506))

for d in (index_dict,idx_pred_value[0],idx_pred_value[1],idx_pred_value[2],idx_pred_value[3],idx_pred_value[4],idx_pred_value[5],idx_pred_value[6],idx_pred_value[7],idx_pred_value[8],idx_pred_value[9],idx_pred_value[10],idx_pred_value[11],idx_pred_value[12],idx_pred_value[13],idx_pred_value[14],idx_pred_value[15],idx_pred_value[16],idx_pred_value[17],idx_pred_value[18],idx_pred_value[19],idx_pred_value[20],idx_pred_value[21],idx_pred_value[22],idx_pred_value[23],idx_pred_value[24],idx_pred_value[25],idx_pred_value[26],idx_pred_value[27],idx_pred_value[28],idx_pred_value[29]):
    for key, value in d.items():
        some_dict[key].append(value)

here idx_pred_value is my list of dictionaries. each dicitonary contains some value with respect to a index value i want to combine all value with same index(key)

although from above code i am able to that but is there any generalize way to access dictionary rather mentioning each dicitionary as individual element of the list

Answer 1

You could do :

list_of_dicts = [index_dict]+[idx_pred_value[i] for i in range(30)]
for d in list_of_dicts:

instead of explicitly writing out the list of dictionaries.
