python - 列表的聚合列

Question

我有以下数据框:

Week     Name    Value
------------------------
1       [A,V,C]  [4,6,2]
2       [A,B,D]  [3,7,1]
3       [X,Y,Z]  [2,5,10]
4       [D,G,M]  [1,2,3]

如何聚合“值”列中的列表？ 例如

Week     Name    Value     sum
------------------------------
1       [A,V,C]  [4,6,2]   12
2       [A,B,D]  [3,7,1]   11
3       [X,Y,Z]  [2,5,10]  17
4       [D,G,M]  [1,2,3]   6

Answer 1

你可以像这样使用apply:

df["sum"] = df["Value"].apply(sum)
