Python, unsupported operand type(s) for *: ‘int‘ and ‘NoneType‘

企业开发 2023-04-08 20:25:24 阅读次数: 0

File "<__array_function__ internals>", line 6, in dot
TypeError: unsupported operand type(s) for *: 'NoneType' and 'int'

使用dot时，左右两边类型不同，函数没有返回值，默认返回None

一般出现：TypeError: unsupported operand type(s) for *: 'NoneType' and 'int'。都是返回值为 None 了
