如何在 tkinter label 中居中文本内容

Question

我正在尝试制作一个非常基本的游戏，您可以在其中移动由普通角色组成的 2D 平面。 但是，我似乎无法将“世界”文本集中在主要的 label 中。

我在想可能有一些隐藏的空白空间，但目前我还没有找到。 特别是在右侧似乎有一个空列或什么的？

任何帮助将不胜感激，请耐心等待我的代码。 干杯!

    #Print map
    width = 10
    coord_values = coordinates.values()
    i=0
    world=""

    for item in coord_values:
        world = world + item + " "
        i += 1
        if i % width == 0:
            world = world + '\n'
        if i == 100:
            world = world[:-1]

    #refresh the label that displays the world
    world_label.place(y=90, x=1)
    world_label.configure(font=("Courier", 24), text=world, bg="AliceBlue", anchor="center", width=20, height=10)


root = Tk() #Create window
root.configure(background="white")


world_label = Label() #Create World Label widget
world_label.pack()

update_world() #Function update_world


root.geometry("1200x800") #Size of window 
root.title('Game 0.1') #Title of window 
root.mainloop() #

以下代码添加的每一行末尾都有额外的空间：

for item in coord_values:
    world = world + item + " "
    ...

要删除多余的空间，请修改 for 循环，如下所示：

for item in coord_values:
    world = world + item + " "
    i += 1
    if i % width == 0:
        world = world[:-1] + '\n'   # use world[:-1] instead of world
world = world[:-1]

但是我建议修改for循环如下：

world = []
for i in range(0, 100, 10):
    world.append(' '.join(coord_values[i:i+10]))
world = '\n'.join(world)
# one-liner for the above:
# world = '\n'.join(' '.join(coord_values[i:i+10]) for i in range(0, 100, 10))
