python和web.py都安装成功，但是复制代码运行检测时报错

python和wen.py都安装成功了，python安装的是3.7版本的，运行复制的代码后，报错，Traceback (most recent call last): RuntimeError: generator raised StopIteration 搜索后可能是版本问题，又重新下载3.6版本，但是运行还是不行，报同样的错误

查看异常信息Traceback (most recent call last):

  File "C:\Users\HHHHH\AppData\Local\Programs\Python\Python37-32\lib\site-packages\web\utils.py", line 526, in take

    yield next(seq)

根据异常提示以找到相应的代码（提示你在C盘...utils.py"中, line 531, in group），如下将：

def my_generator():

    ...

    yield next(it)

    ...

修改为：

def my_generator():

    try:

        ...

        yield next(it)

        ...

    except StopIteration:

        return

注意缩进问题
