python - 如何拆分列表中的字符串列表？

Question

让我们来看看:

my_list=[["a","b","c"],["d","e","f"],["g","h","i"],["j","k","l"]]

我正在寻找的结果:

0. a    _ b    (c)
1. d    _ e    (f)
2. g    _ h    (j)
3. j    _ k    (l)

Answer 1

要在控制台中准确打印输出，请迭代外部列表并使用 enumerate 和 str.format:

values = [["a","b","c"],["d","e","f"],["g","h","i"],["j","k","l"]]

for i, x in enumerate(values):
    print("{}. {}    _ {}    ({})".format(i, *x))
# 0. a    _ b    (c)
# 1. d    _ e    (f)
# 2. g    _ h    (i)
# 3. j    _ k    (l)
