fill 控件填充方式

padx - 设置水平方向的外边距

from tkinter import *
root = Tk()
w = Label(root, text="Red Sun", bg="red", fg="white")
w.pack(fill=X,padx=10)
w = Label(root, text="Green Grass", bg="green", fg="black")
w.pack(fill=X,padx=50)  #  水平外边距
w = Label(root, text="Blue Sky", bg="blue", fg="white")
w.pack(fill=X,padx=10)
mainloop()

pady - 设置竖直方向的外边距

from tkinter import *
root = Tk()
w = Label(root, text="Red Sun", bg="red", fg="white")
w.pack(fill=X,pady=10)
w = Label(root, text="Green Grass", bg="green", fg="black")
w.pack(fill=X,pady=10)
w = Label(root, text="Blue Sky", bg="blue", fg="white")
w.pack(fill=X,pady=10)
mainloop()

ipadx - 设置水平方向的内边距

from tkinter import *
root = Tk()
w = Label(root, text="Red Sun", bg="red", fg="white")
w.pack()
w = Label(root, text="Green Grass", bg="green", fg="black")
w.pack(ipadx=50)
w = Label(root, text="Blue Sky", bg="blue", fg="white")
w.pack()
mainloop()

ipady - 设置竖直方向的内边距

from tkinter import *
root = Tk()
w = Label(root, text="Red Sun", bg="red", fg="white")
w.pack()
w = Label(root, text="Green Grass", bg="green", fg="black")
w.pack(ipadx=10)
w = Label(root, text="Blue Sky", bg="blue", fg="white")
w.pack(ipady=10)
mainloop()

使用pack（）函数，可以指定位置

import tkinter as tk
import random

root = tk.Tk()
# width x height + x_offset + y_offset:
root.geometry("170x200+30+100")   # 设置初始窗口大小，并且初始窗口的位置
root.resizable(width=False,height=False)

languages = ['Python', 'Perl', 'C++', 'Java', 'Tcl/Tk']
labels = range(5)
for i in range(5):
    ct = [random.randrange(256) for x in range(3)]
    brightness = int(round(0.299 * ct[0] + 0.587 * ct[1] + 0.114 * ct[2]))
    ct_hex = "%02x%02x%02x" % tuple(ct)
    bg_colour = '#' + "".join(ct_hex)
    l = tk.Label(root,
                 text=languages[i],
                 fg='White' if brightness < 120 else 'Black',
                 bg=bg_colour)
    l.place(x=20, y=30 + i * 30, width=120, height=25)

root.mainloop()
