考虑以下代码:

if value and self.fps_display is None:
    self.fps_display = clock.ClockDisplay()
elif not value and self.fps_display is not None:
    self.fps_display.unschedule()
    # Do this
    del self.fps_display
    # or this
    self.fps_display = None
    # or leave both in ?

哪个更好的python清理？

del在Python中调用变量.这会立即释放分配的内存还是等待垃圾收集器收集？与java一样,显式调用del对释放内存的时间没有影响.
