fuz()

当我尝试获取 HTML 表单输入并将其作为输入发送到 python 时，我收到此错误TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'任何人都知道为什么？也许是因为那里的温度和嗡嗡声输入？当我删除 int() 代码也无法运行......

解决方案

这是因为该值为 NoneType （即函数没有返回任何内容）。例如：

temp = int(form.getvalue('temp'))

form.getvalue('temp') 正在返回 NoneType

'temp'字段是否可能不存在？
