[英]can't find a solution to the problem in this function def interval()
I'm learning python right now and following this book "Beginning Python" I've got stuck at this example:我现在正在学习 python 并遵循这本书“Beginning Python”,我被这个例子困住了:
def interval(start, stop=None, step=1):
if stop is None:
start, stop = 0, start
result = []
i = start
while i < stop:
result.append(i)
i += stop
return result
If I call this function let say interval(10)
it doesn't print anything.如果我称它为 function 让我们说
interval(10)
它不会打印任何东西。 I code in PyCharm Python 3.9我在 PyCharm Python 3.9 中编码
You just had a typo in your while loop when incrementing your step, ie i += stop
.增加步数时,您的 while 循环中出现了拼写错误,即
i += stop
。 Instead of stop
use step.
而不是
stop
使用step.
def interval(start, stop=None, step=1):
if stop is None:
start, stop = 0, start
result = []
i = start
while i < stop:
result.append(i)
i += step
return result
print(interval(10))
Output: Output:
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
