怎么用python读文件

fi = open('wenben.txt', 'r', encoding='utf-8')

data = fi.read()

print(data)

我是测试文本

def open(file: Union[str, bytes, int], mode: str = ..., buffering: int = ..., encoding: Optional[str] = ...,

            errors: Optional[str] = ..., newline: Optional[str] = ..., closefd: bool = ...,

            opener: Optional[Callable[[str, int], int]] = ...) -> IO[Any]: ...
