TKinter
Python 的 GUI 库非常多，之所以选择 Tkinter，一是最为简单，二是自带库，不需下载安装，随时使用，跨平台兼容性非常好，三则是从需求出发的，Python 在实际应用中极少用于开发复杂的桌面应用，毕竟，Python 的各种 GUI 工具包都“一般得很”，不具备优势。
案例一
Label & Button 标签和按钮
import tkinter as tk window = tk.Tk() # 实例化Tkwindow.title("muy window") # 设置标题window.geometry("200x100") # 设置窗口的大小var1 = tk.StringVar() # 定义tk变量l1 = tk.Label(window, textvariable=var1, bg="green", font=("Arial", 12), width=15, height=2) # 设置标签，内容显示为var1变量l1.pack() # 摆放这个标签hit_me1 = Falsedef hit_me(): global hit_me1 if not hit_me1: hit_me1 = True var1.set("this is tk") # 给变量赋值 else: hit_me1 = False var1.set("this is tk, too")b1 = tk.Button(window, text="hit me", width=15, height=2, command=hit_me) # 点击按钮，运行hit_me这个函数b1.pack()window.mainloop() # 显示窗口案例二
Entry & Text 输入和文本框
import tkinter as tk window = tk.Tk() # 实例化Tkwindow.title("muy window") # 设置标题window.geometry("200x150") # 设置窗口的大小e = tk.Entry(window, show=None) # 如果输入密码的话，show="*"e.pack()def insert_point(): var = e.get() # 得到文本输入框的值 t.insert("insert", var) # 文本放到光标位置def insert_end(): var = e.get() t.insert("end", var) # 将文本放到文本框的末尾 # t.insert(1.1, var) # 将文本放到第一行第一列b1 = tk.Button(window, text="insert point", width=15, height=2, command=insert_point).pack() # 定义一个按钮，显示在光标位置插入文本b2 = tk.Button(window, text="insert end", width=15, height=2, command=insert_end).pack() # 在末尾出插入t = tk.Text(window, height=2, width=15)t.pack() # 注意不能一行写完，pack要写在下一行window.mainloop() # 显示窗口案例三
