Else statement executed even if break is triggered in while loop

Question

I have a while loop which checks for the rising edge of the variable Accessory2. My code is the following:

            # Check for rising edge of ACC2
    while (currentTime.Value - StartTime) < TimeOutValue:
        if Accessory2.Value == 1:
            Acc2StartTime = currentTime.Value
            print rttPrefix + "ACC2 output to ON"
            break
        yield None
    else:
        print rttPrefix + "No ACC2 output"
        DynamicFlag.Value = -2

However, when the variable Accessory2 goes up, the break condition stops the if statement but the else statement is also executed. Any idea why ?

The output is the following:

*RTT:* ACC2 output to ON
*RTT:* No ACC2 output

Answer 1

也许您只是多次执行（或继续）while循环，而第一次执行将打印您的第一行，而随后的执行将打印第二行。

Answer 2

您的else语句与while循环的缩进级别相同，因此不在其中。
