我希望每次传感器检测到15厘米范围内的任何东西时，程序都能循环

Question

代码如下：

def check_ultra():
    global arduinoSerialData, y, i, x
    while True:
        if arduinoSerialData.inWaiting() > 1:
            myData = arduinoSerialData.readline()
            myData = str(myData)
            myData = myData.replace("b'", '')
            myData = myData.replace("\\r\\n'", str(0))
            myData = myData.replace("\\r00.000", str(0))
            myData = myData.replace("\\r00.000", str(0))
            if "c" in myData:
                myData = myData.replace("c", str(0))

                if y == 1:
                    y = 3
                    if float(myData) > 15:
                        x = 0
                    return y, x
                else:
                    if float(myData) < 15 and float(myData) > 1:
                        y = 1
                        x = 0
                        return y, x
            elif "a" in myData:
                myData = myData.replace("a", str(0))
                if y == 2:
                    y = 3
                    if float(myData) > 15:
                        x = 0
                    return y, x
                else:
                    if float(myData) < 15 and float(myData) > 1:
                        y = 2
                        x = 0
                        return y, x
            else:
                y = 0
                return y


set_servo1_angle(0)
set_servo2_angle(90)
go_out_count = 0
m1 = 0
count = 3
y = 0
i = 0
x = 0
while y == None or y == 0 or x == 1:
    # i = 0
    # y = None
    check_ultra()
    if y == 1 and x == 0:
        print("1")
        sleep(2)
    elif y == 2 and x == 0:
        print('2')
        sleep(2)

当前的功能是每次传感器1被阻止时打印1，但随后结束代码。我希望这样，每次我阻塞传感器时，它都会打印相应的打印语句，无论我阻塞传感器多少次。我尝试添加许多变量来帮助解决问题，但都不起作用。如何使循环不断重复

Answer 1

“break”语句结束while循环，因此请尝试将其替换为“pass”，如下所示：

elif y == 2:
   print('2')
   pass
