Python可视化界⾯编程⼊门具体实现代码如所⽰：
（1）普通可视化界⾯编程代码⼊门：
import sys
from PyQt5.QtWidgets import QWidget,QApplication #导⼊两个类来进⾏程序界⾯编程
if __name__==\"__main__\": #创建⼀个Application的类 app=QApplication(sys.argv) #创建⼀个窗⼝ w=QWidget()
#设置窗⼝的尺⼨⼤⼩ w.resize(400,200) # 移动窗⼝
w.move(300,300)
#设置窗⼝的标题
w.setWindowTitle(\"得⼀个基于PyQt5的桌⾯应⽤\") #显⽰窗⼝ w.show()
#静进⼊程序的主循环，并且通过exit函数确保主循环的安全结束 sys.exit(app.exec_()) #⼀⼀直在桌⾯上显⽰窗⼝形状
#QTdesigner和pyGUI扩展⼯具在pycharm平台中的的安装和配置
#直接安装QT软件或者安装anaconda开发环境之后就会在电脑安装好QTdesigner.exe⽂件，之后pycharm⾥⾯配置扩展⼯具external tool⽂件，便可以⽅便在pycharm⾥⾯直接启动
在pycharm⾥⾯配置扩展⼯具external toolQTdesigne和pyGUI（可以将ui⽂件直转换为.py⽂件，建⽴设计的可视化界⾯的⼤类直接进⾏
配置好之后设计可视化界⾯的步骤是：
（1）利⽤pychar⾥⾯的QTdesigner扩展⼯具进⾏可视化界⾯的设计，然后将其保存为.ui⽂件；
（2）使⽤pyGUI扩展⼯具将设计好的可视化界⾯.ui⽂件转换为.py⽂件，⽣成⼀个建⽴的可视化模板⼤类，直接进⾏调⽤即可。
具体代码如下所⽰：
import sys
import mainwinvertical #导⼊相应的设计好的QTdesigner主窗⼝的类，然后即可直接进⾏展⽰（由ui⽂件经过PYGUI扩展⼯具转换⽽来）from PyQt5.QtWidgets import QApplication,QMainWindow
if __name__==\"__main__\": app=QApplication(sys.argv)
mainwin=QMainWindow() #创建⼀个窗⼝
ui=mainwinvertical.Ui_MainWindow() #创建⼀个QTdesigner的类
ui.setupUi(mainwin) #将对象直接进⾏运⾏设置函数，向主窗⼝上添加控件 mainwin.show() #展⽰出来窗⼝的形式
sys.exit(app.exec_()) #承接开头语句，⽤来实时的显⽰窗⼝
其中mainwinvertical类的具体代码如下：（由QTdesigner设计好可是换界⾯，然后直接⽤pyGUi扩展⼯具转换为.python代码⽂件）
# -*- coding: utf-8 -*-# Form implementation generated from reading ui file 'mainwinvertical.ui'#
# Created by: PyQt5 UI code generator 5.13.2#
