Question

下面显示的代码是我用来控制7种不同的9g伺服电机的代码。它们连接到adafruit伺服帽，连接到树莓派3。所有7个定义都可以并行或同时运行。使用我拥有的代码，这7个定义确实可以并行运行，但是并不一致。我的意思是，该代码有时会完全起作用，而其他时候，伺服器会在操作过程中停止。似乎我需要使用多处理功能而不是Thread功能来获得更多的计算能力。回到主要问题，是否可以在python中使用具有多个定义的并行处理函数，该怎么做？谢谢

if __name__ == '__main__':
    Thread(target = func1).start()
    Thread(target = func2).start()
    Thread(target = func3).start()
    Thread(target = func4).start()
    Thread(target = func5).start()
    Thread(target = func6).start()
    Thread(target = func7).start()

有没有办法在python 2.7中的多个定义之间进行并行处理？
