Pandas具有可变子数组长度的sum列，并向结果中添加更多列

import pandas as pd

data = {'sum': [[1, 2, 3], [4, 5], [6, 7, 8, 9]]}
df = pd.DataFrame(data)

df['sum_sum'] = df['sum'].apply(sum)

import pandas as pd

data = {'sum': [[1, 2, 3], [4, 5], [6, 7, 8, 9]]}
df = pd.DataFrame(data)

df['sum_sum'] = df['sum'].apply(sum)
df['new_column1'] = [10, 20, 30]
df['new_column2'] = ['a', 'b', 'c']

print(df)

           sum  sum_sum  new_column1 new_column2
0     [1, 2, 3]        6           10           a
1        [4, 5]        9           20           b
2  [6, 7, 8, 9]       30           30           c
