取出二维元组的第二维度

可以使用列表推导式或者循环来取出二维元组的第二维度。

1. 使用列表推导式

t = [(1, 2), (3, 4), (5, 6)]
second_dimension = [x[1] for x in t]
print(second_dimension)  # 输出 [2, 4, 6]

2. 使用循环

t = [(1, 2), (3, 4), (5, 6)]
second_dimension = []
for x in t:
    second_dimension.append(x[1])
print(second_dimension)  # 输出 [2, 4, 6]
