python tkinter canvas 根据选定的组合框值使用多个条件移动图像

Question

Please see the image for your reference你好我正在做我的 tkinter 毕业设计，我是 python 的新手。我想根据选定的组合框值从 1 到 5 将指定的棋子移动到风险矩阵可能性和影响矩阵内。如果从影响框中选择 1，从可能性框中选择 5，则棋子将移动到相应的主矩阵框架canvas。我在网上做了一项研究，我只能使用猴子修补方法移动一个条件。但是，我还有其他 24 个条件，猴子修补程序只会对一个或最后一个 if 条件起作用。我尝试了多个 elif 语句但无济于事。我希望有人能帮我解决这个问题。

    global chesspiece
    # Get the current object position
    x, y, *_ = self.bbox(_object)
    # Move the object
    self.move(_object, new_x-x, new_y-y)
# Monkey patch the `abs_move` method
tk.Canvas.abs_move = abs_move

Answer 1

为了解决移动棋子的问题，我会使用与这两个键相同的键创建额外的字典：

impactDict = {'Catstrophic': 5, 'Severe': 4, 'Major': 3, 'Moderate': 2, 'Minor':1}
likelihoodDict = {'Almost Certain': 5, 'likely': 4, 'possible': 3, 'unlikely': 2, 'rare':1}

但将值设置为您要将棋子移动到的位置的坐标。然后每次调用 move_image 时，您都可以使用那些字典来移动棋子。这是我的意思的一个例子：

def move_image():
    global canvas
    global chesspiece
    likelyhoodDict_x = {'Almost Certain': 560, 'likely': 465, 'possible': 365, 'unlikely': 270, 'rare': 170}
    impactDict_y = {'Catstrophic': 0, 'Severe': 50, 'Major': 100, 'Moderate': 150, 'Minor': 208}
    likelyhood = combo_likelihood.get()
    impact = combo_impact.get()
    if impact != '' and likelyhood != '':
        totalvalues = int(impactDict[combo_impact.get()]) * int(likelihoodDict[combo_likelihood.get()])

    total.configure(text="Risk score : " + str(totalvalues))

    if likelyhood in likelyhoodDict_x and impact in impactDict_y:
        canvas.abs_move(canvas, chesspiece, likelyhoodDict_x[likelyhood], impactDict_y[impact])

    if impact == 'Minor' and likelyhood == 'rare':
        return "negligible risk"
