lists = [[] for _ in range(len(str(all_row_lists)))] for i, string in enumerate(str(all_row_lists)): nums = [int(num) for num in string.split(',')] for j, num in enumerate(nums): lists[j].append(num) lst_lisn = [] for lst in lists: lst_lisn.append(lst) print(lst_lisn) 如果有空值就跳过

如果要在提取数字时跳过空值，你可以使用以下代码进行修改：

all_row_lists = ['11,13', '15,19', '', '23,']

lists = [[] for _ in range(len(all_row_lists))]

for i, string in enumerate(all_row_lists):
    if string:
        nums = [int(num) for num in string.split(',') if num.strip()]
        for j, num in enumerate(nums):
            lists[j].append(num)

lst_lisn = []
for lst in lists:
    lst_lisn.append(lst)
print(lst_lisn)

这样，将会跳过空值，并且不会将空值添加到对应的列表中。输出结果将会是：

[[11, 15, 23], [13, 19]]

这样，空值对应的列表将会是空的，而其他列表将会包含对应的数字。
