Python 采用easydriver和rasberry pi的步进电机控制

我最近开始了我的Rpi项目。
我需要一些关于修改代码的帮助或建议

我有一个（Pi，+easydriver V4.4，+nema 17步进电机）
使用车身控制模块布局

我需要一个具有间隔的无限嵌套循环@

我希望我的步进器步进200步，然后停止0.1秒，然后再步进200步，等等（无限循环）

感觉像个傻瓜。。。我在睡觉的时候有点不正常！ 这就是我创建循环的方式：

loopinfinity = 1
# Do some steps.(800) full revolution
def step_motor():
  for i in range(120):
    stepper.step()

while loopinfinity > 0:
  try:
     step_motor()
     time.sleep(0.07) #this is in seconds
  except KeyboardInterrupt :
     loopinfinity -=1
     print("stopped")

什么是Easydriver\u master？那不是你要导入的任何东西。。。还有，这里有什么问题或错误？很抱歉让它变得如此复杂。改进了格式，简化了问题

loopinfinity = 1
# Do some steps.(800) full revolution
def step_motor():
  for i in range(120):
    stepper.step()

while loopinfinity > 0:
  try:
     step_motor()
     time.sleep(0.07) #this is in seconds
  except KeyboardInterrupt :
     loopinfinity -=1
     print("stopped")
