一、环境搭建

直接pip安装即可：

pip install PyQt5

pip install pyqt5-tools

二、Qt Designer设计GUI

Qt Designer 是通过拖拽的方式放置控件，并实时查看控件效果进行快速UI设计。最终生成.ui文件，可以通过pyuic5工具转换成.py文件。

打开designer.exe；界面如下

三、生成界面代码

        使用命令：pyuic5 -o Test.py Test.ui

# -*- coding: utf-8 -*-

# Form implementation generated from reading ui file 'Test.ui'
#
# Created by: PyQt5 UI code generator 5.15.4
#
# WARNING: Any manual changes made to this file will be lost when pyuic5 is
# run again.  Do not edit this file unless you know what you are doing.


from PyQt5 import QtCore, QtGui, QtWidgets


class Ui_Form(object):
    def setupUi(self, Form):
        Form.setObjectName("Form")
        Form.resize(730, 478)
        self.pushButton = QtWidgets.QPushButton(Form)
        self.pushButton.setGeometry(QtCore.QRect(70, 190, 93, 28))
        self.pushButton.setObjectName("pushButton")
        self.pushButton_2 = QtWidgets.QPushButton(Form)
        self.pushButton_2.setGeometry(QtCore.QRect(230, 190, 93, 28))
        self.pushButton_2.setObjectName("pushButton_2")
        self.label = QtWidgets.QLabel(Form)
        self.label.setGeometry(QtCore.QRect(0, 20, 61, 16))
        font = QtGui.QFont()
        font.setPointSize(10)
        self.label.setFont(font)
        self.label.setAlignment(QtCore.Qt.AlignCenter)
        self.label.setObjectName("label")
        self.textBrowser = QtWidgets.QTextBrowser(Form)
        self.textBrowser.setGeometry(QtCore.QRect(70, 10, 391, 31))
        self.textBrowser.setObjectName("textBrowser")

        self.retranslateUi(Form)
        QtCore.QMetaObject.connectSlotsByName(Form)

    def retranslateUi(self, Form):
        _translate = QtCore.QCoreApplication.translate
        Form.setWindowTitle(_translate("Form", "Form"))
        self.pushButton.setText(_translate("Form", "PushButton"))
        self.pushButton_2.setText(_translate("Form", "PushButton"))
        self.label.setText(_translate("Form", "输入1"))

四、 创建调用该界面代码

        文件call_Test.py

#导入程序运行必须模块
import sys
#PyQt5中使用的基本控件都在PyQt5.QtWidgets模块中
from PyQt5.QtWidgets import QApplication, QMainWindow
#导入designer工具生成的login模块
from Test import Ui_Form

class MyMainForm(QMainWindow, Ui_Form):
 def __init__(self, parent=None):
  super(MyMainForm, self).__init__(parent)
  self.setupUi(self)
if __name__ == "__main__":
 #固定的，PyQt5程序都需要QApplication对象。sys.argv是命令行参数列表，确保程序可以双击运行
 app = QApplication(sys.argv)
 #初始化
 myWin = MyMainForm()
 #将窗口控件显示在屏幕上
 myWin.show()
 #程序运行，sys.exit方法确保程序完整退出。
 sys.exit(app.exec_())

五、 VScode运行效果
