python - 计算器上的列间距

问题描述

我刚刚开始编码，并且一直在使用 python3 tkinter 为计算器编写脚本，但我似乎无法让这些列很好地彼此相邻。

计算器布局

e = Entry(root, width=35, borderwidth=5)
e.grid(row=0, column=0, columnspan=3, padx=10, pady=10)

button_1 = Button(root, text='1', padx=40, pady=20, command=lambda: button_click(1))
button_2 = Button(root, text='2', padx=40, pady=20, command=lambda: button_click(2))
button_3 = Button(root, text='3', padx=40, pady=20, command=lambda: button_click(3))
button_4 = Button(root, text='4', padx=40, pady=20, command=lambda: button_click(4))
button_5 = Button(root, text='5', padx=40, pady=20, command=lambda: button_click(5))
button_6 = Button(root, text='6', padx=40, pady=20, command=lambda: button_click(6))
button_7 = Button(root, text='7', padx=40, pady=20, command=lambda: button_click(7))
button_8 = Button(root, text='8', padx=40, pady=20, command=lambda: button_click(8))
button_9 = Button(root, text='9', padx=40, pady=20, command=lambda: button_click(9))
button_0 = Button(root, text='0', padx=40, pady=20, command=lambda: button_click(0))
button_add = Button(root, text='+', padx=40, pady=20, command=button_add)
button_equal = Button(root, text='=', padx=91, pady=20, command=button_equal)
button_clear = Button(root, text='Clear', padx=79, pady=20, command=button_clear)

button_subtract = Button(root, text='-', padx=41, pady=20, command=button_subtract)
button_multiply = Button(root, text='*', padx=39, pady=20, command=button_multiply)
button_divide = Button(root, text='/', padx=39, pady=20, command=button_divide)

button_1.grid(row=3, column=0)
button_2.grid(row=3, column=1)
button_3.grid(row=3, column=2)

button_4.grid(row=2, column=0)
button_5.grid(row=2, column=1)
button_6.grid(row=2, column=2)

button_7.grid(row=1, column=0)
button_8.grid(row=1, column=1)
button_9.grid(row=1, column=2)

button_0.grid(row=4, column=0)
button_add.grid(row=5, column=0)
button_equal.grid(row=5, column=1, columnspan=2)
button_clear.grid(row=4, column=1, columnspan=2)

button_subtract.grid(row=6, column=0)
button_multiply.grid(row=6, column=1)
button_divide.grid(row=6, column=2)

我已经尝试调整它们的大小以使所有按钮都相等，但列之间仍然存在间隙。这是与计算器外观相关的所有代码。我在 mac os 上使用 python 3 tkinter 和 pycharm，任何帮助将不胜感激。

解决方案

为每个小部件设置一个sticky，在您的代码末尾添加这个（当您的 GUI 只有这些小部件时，我建议您将所有按钮放在一个. 并Frame使用它Frame.winfo_children()来执行此操作）：

xxx
for i in root.winfo_children():
    i.grid(sticky="nwes")

root.mainloop()
