The simplest kind of layout: (specify the side parameter)
tk.Label(window, text='顶部label',bg='green').pack(side='top') # 上
tk.Label(window, text='底部label',bg='green').pack(side='bottom') # 下
tk.Label(window, text='左边label',bg='green').pack(side='left') # 左
tk.Label(window, text='右边label',bg='green').pack(side='right') # 右
Effect:
If it is used directly: (Do not specify the side parameter)
For example:
'''
创建两个label，pack()不加参数效果
'''
l1 = tk.Label(window, text='hello world', bg='gray', font=('Arial', 12), width=30, height=2)
l1.pack()
l2=tk.Label(window, text='hello world', bg='gray', font=('Arial', 12), width=30, height=2)
l2.pack()
The effect is shown in the figure (the default parameter is side='top'):
