如何在Python中指定列的范围，而不是逐个输入？

my_list = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
sub_list = my_list[2:6]  # 获取索引2到索引6之间的元素
print(sub_list)  # 输出: [3, 4, 5, 6]

my_string = "Hello, World!"
sub_string = my_string[7:12]  # 获取索引7到索引12之间的字符
print(sub_string)  # 输出: World

my_tuple = (1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
sub_tuple = my_tuple[3:8:2]  # 获取索引3到索引8之间，步长为2的元素
print(sub_tuple)  # 输出: (4, 6, 8)
