Question

下面的代码可以用单层结构完成吗？

five_fifteen = []

for x in range(5,15):
    five_fifteen.append(x)
    print (five_fifteen)

谢谢

Answer 1

如果要创建新列表：

five_fifteen = list(range(5, 15))

如果要扩展现有列表：

five_fifteen.extend(range(5, 15))

Answer 2

当然，但我没有真正地指出要点

five_fifteen = list(range(5, 16))
five_fifteen = [i for i in range(5, 16)]

最简单的方法应该是使用 list（）本身，或使用列表理解

使用map或lambda函数可以做到吗
