while循环(Python)

Question

如果我想说一段时间循环(比如：while time is greater than or equal to 0 )，它会被写成while time > or == 0吗？还是没办法这么做？

Answer 1

使用while time >= 0 (相当于while time > 0 or time == 0)

>>> 0 >= 0
True
>>> 1 >= 0
True
>>> -1 >= 0
False

Answer 2

它将是：

while time >= 0:
    pass
    #here be dragons

Answer 3

在Python示例中计数：

time = 0 
while time < 100: 
    time = time + 1 
    print time
