反斜杠“\”有参与什么运算吗？在PID 的代码中看到

[cghq]

附上原码：

“derivative = self._last_derivative + \
                                     ((delta_time / (self._RC + delta_time)) * \
                                        (derivative - self._last_derivative))”

[cghq]

derivative = self._last_derivative + \
                                     ((delta_time / (self._RC + delta_time)) * \
                                        (derivative - self._last_derivative))

粘贴提交问题以后“\”就自动消失了......

[kidswong999]

            derivative = self._last_derivative + \
                                     ((delta_time / (self._RC + delta_time)) * \
                                        (derivative - self._last_derivative))

这里的没什么意义，就是一行写不下，换一行写。
