Question

在我的代码中，它应该是一个被操纵的魔法8球。按A应显示“是！”，按B应显示“否” 但每次都显示“是的！”没有按任何按钮。

from microbit import *
import random

frameq = Image("00000:""00000:""00900:""00000:""00000")
framew = Image("00000:""09990:""09390:""09990:""00000")
framee = Image("99999:""93339:""93339:""93339:""99999")
framer = Image("33333:""33333:""33333:""33333:""33333")
framet = Image("22222:""22222:""22222:""22222:""22222")
framey = Image("11111:""11111:""11111:""11111:""11111")
frames = [frameq, framew, framee, framer, framet, framey]
answers = [
    "It is certain",
    "It is decidedly so",
    "Without a doubt",
    "Yes, definitely",
    "You may rely on it",
    "As I see it, yes",
    "Most likely",
    "Outlook good",
    "Yes",
    "Signs point to yes",
    "Reply hazy try again",
    "Ask again later",
    "Better not tell you now",
    "Cannot predict now",
    "Concentrate and ask again",
    "Don't count on it"
    "My reply is no",
    "My sources say no",
    "Outlook not so good",
    "Very doubtful",
]
apress = False
bpress = False
while True:
    if button_a.is_pressed:
        bpress = False
        apress = True
    elif button_b.is_pressed:
        apress = False
        bpress = True
    display.show("8")
        if accelerometer.was_gesture("shake") and apress is True:
        display.clear()
        display.show(frames, loop=False, delay=250)
        sleep(1000)
        display.show("Yes!")
        apress = False
    elif accelerometer.was_gesture("shake") and bpress is True:
        display.clear()
        display.show(frames, loop=False, delay=250)
        sleep(1000)
        display.show("No.")
        bpress = False
    elif accelerometer.was_gesture("shake"):
        display.clear()
        display.show(frames, loop=False, delay=250)
        sleep(1000)
        display.scroll(random.choice(answers))

它没有显示错误消息，只显示“是！”每一次我都动摇。顺便说一句，“是的！”不在答案数组中，只有“是”，我总是看到！。

Answer 1

如果没有更多的背景，人们只能假设问题是什么。确保is_pressed不是函数：

if button_a.is_pressed:
    bpress = False
    apress = True
elif button_b.is_pressed:
    apress = False
    bpress = True

如果is_pressed是一个函数，那么button_a.is_pressed将始终为True因此apress始终为True因此您将总是打印'Yes!'。

尝试将上述代码更改为

if button_a.is_pressed():
    bpress = False
    apress = True
elif button_b.is_pressed():
    apress = False
    bpress = True

否则，您编程调试。在不同的执行路径中添加print语句，看看每个if语句是True的原因。

谢谢DeepSpace！经过一些修饰，这是我的最终代码。对不起，我没有说清楚，但这是一个可以操纵的神奇的8球。按A或B. 这是最终的代码：

from microbit import *
import random

frameq = Image("00000:""00000:""00900:""00000:""00000")
framew = Image("00000:""09990:""09390:""09990:""00000")
framee = Image("99999:""93339:""93339:""93339:""99999")
framer = Image("33333:""33333:""33333:""33333:""33333")
framet = Image("22222:""22222:""22222:""22222:""22222")
framey = Image("11111:""11111:""11111:""11111:""11111")
frames = [frameq, framew, framee, framer, framet, framey]
answers = [
    "It is certain",
    "It is decidedly so",
    "Without a doubt",
    "Yes, definitely",
    "You may rely on it",
    "As I see it, yes",
    "Most likely",
    "Outlook good",
    "Yes",
    "Signs point to yes",
    "Reply hazy try again",
    "Ask again later",
    "Better not tell you now",
    "Cannot predict now",
    "Concentrate and ask again",
    "Don't count on it"
    "My reply is no",
    "My sources say no",
    "Outlook not so good",
    "Very doubtful",
]
apress = False
bpress = False
while True:
    if button_a.is_pressed():
        bpress = False
        apress = True
    elif button_b.is_pressed():
        apress = False
        bpress = True
    display.show("8")
    if accelerometer.was_gesture("shake"):
        if apress:
            display.clear()
            display.show(frames, loop=False, delay=250)
            sleep(1000)
            display.show("Yes!")
            apress = False
        elif bpress:
            display.clear()
            display.show(frames, loop=False, delay=250)
            sleep(1000)
            display.show("No.")
            bpress = False
        else:
            display.clear()
            display.show(frames, loop=False, delay=250)
            sleep(1000)
            display.scroll(random.choice(answers))

我在python中的代码出了什么问题？
