减少循环

Question

我想要一个像这样的for循环：

for counter in range(10,0):
       print counter,

，输出应为10 9 8 7 6 5 4 3 2 1

Answer 1

a = " ".join(str(i) for i in range(10, 0, -1))
print (a)

Answer 2

查看range文档，您必须定义一个否定步骤：

>>> range(10, 0, -1)
[10, 9, 8, 7, 6, 5, 4, 3, 2, 1]

Answer 3

你需要给出范围-1步

 for i in range(10,0,-1):
    print i

Answer 4

范围步长应为-1

   for k in range(10,0,-1):
      print k
