Python显示画面需要什么 python3图形界面

【注: 以下示例python3版本】

示例一：

import tkinter as tk
app = tk.Tk()
app.title("FishC Demo")
theLable = tk.Label(app, text="我的第二个窗口程序",width=20,height=10)#标签控件；可以显示文本和位图
theLable.pack()
app.mainloop()

运行结果：

示例二：

import tkinter as tk
class App: #定义类
def __init__(self, master):
frame = tk.Frame(master)#定义窗体框架
frame.pack(side=tk.RIGHT, padx=100,pady=100)
#定义按钮
self.hi_there = tk.Button(frame, text="打招呼",bg="red" ,fg='green',command=self.say_hi)
self.hi_there.pack(padx=10, pady=10)#位置
def say_hi(self):
print("Hi! 大家好,终于我跟大家见面了。")
root = tk.Tk()
app = App(root)
root.mainloop()

运行结果：

示例三

from tkinter import *
root = Tk()

textLabel = Label(root,text="有些心疼，又带着欣喜。\n她那么简单，不好看，却努力的开着，\

\n为了迎合清风掠心的柔情，一直努力的开着，\n半盏清歌的招摇，\

肆意葱茏。\n而我，恰巧路过。于是，\n喜意便盈盈的生了起来，带\

着异样的温暖和朴素，\n将心，都染了湿湿的绿，盎然的，\n万千端倪。", justify=LEFT, padx=10) #Label 标签控件；可以显示文本和位图

textLabel.pack(side=LEFT)
photo = PhotoImage(format="png",file=r"C:\Users\Administrator\Desktop\123 (2).png")#PhotoImagecan be used for GIF and PPM/PGM color bitmaps
imgLabel = Label(root, image=photo)
imgLabel.pack(side=RIGHT)
mainloop()

运行结果：

文字排版不啥样，只是展示效果而已，请原谅！

示例四

from tkinter import *
root = Tk()
photo = PhotoImage(file=r"C:\Users\Administrator\Desktop\123.png")
theLable = Label(root,
text='Hello',
justify = LEFT,
image=photo,
compound=CENTER,
font=("黑体",20),
fg = "red")
theLable.pack()
mainloop()

运行结果：

展示效果而已！

示例五

from tkinter import *
def callback():
var.set('吹吧你，我才不信呢')
root = Tk()
frame1 = Frame(root)#Frame 框架控件；在屏幕上显示一个矩形区域，多用来作为容器
frame2 = Frame(root)
var = StringVar() #设置字符串
var.set("你所下载的影片含有末成人限制内容，\n请满18周岁后再点击观看")
textLabel = Label(frame1,
textvariable = var,
justify = LEFT)
textLabel.pack(side=LEFT)
photo = PhotoImage(file=r"C:\Users\Administrator\Desktop\123 (2).png")
imgLabel = Label(frame1,text="图片一", image=photo)
imgLabel.pack(side=RIGHT)
theButton = Button(frame2,text="我已满18周岁", command=callback) #定义一个按钮
theButton.pack()
frame1.pack(padx=10, pady=10)#定义位置
frame2.pack(padx=50, pady=50)
mainloop()

运行结果

示例六
