前言

猜单词：将单词存在列表中，使用random随机在列表中选择一个单词存入全局列表A，将用户猜的单词也存在全局列表A，当A[0]==A[1]时，判断猜单词正确。
代码还可以优化，例如猜单词不用全部写，写缺少的字母就可以；计分等。
效果：

一、实现步骤

第一步：点击VS2019–>工具–>QtDesigner
注：VS2019配置PyQt5参考链接https://blog.csdn.net/Target_MIT/article/details/105884640

第二步：在pyqt5画界面

第三步：将ui界面添加到项目中
点击图中的红框框处

第四步：将ui界面生成代码

第五步：添加代码
给按钮添加使用connect连接自己创建的槽方法实现相关功能

二、代码

代码如下：

from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtWidgets import QApplication,QMainWindow,QPushButton,QWidget
import random
import sys

message = ['1','2']
class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(354, 245)

        self.centralwidget.setObjectName("centralwidget")
        self.gridLayout = QtWidgets.QGridLayout(self.centralwidget)
        self.gridLayout.setObjectName("gridLayout")
        self.label = QtWidgets.QLabel(self.centralwidget)
        self.label.setObjectName("label")
        self.gridLayout.addWidget(self.label, 0, 0, 1, 2)
        self.pushButton = QtWidgets.QPushButton(self.centralwidget)
        self.pushButton.setObjectName("pushButton")
        self.gridLayout.addWidget(self.pushButton, 1, 0, 1, 1)

        MainWindow.setStatusBar(self.statusbar)

        self.pushButton.clicked.connect(self.GuessWordclick)
        self.pushButton_2.clicked.connect(self.GuessJudge)

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

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate

        self.label.setText(_translate("MainWindow", "欢迎来到猜单词游戏"))
        self.pushButton.setText(_translate("MainWindow", "开始游戏"))
        self.pushButton_2.setText(_translate("MainWindow", "确定"))

    def GuessWordclick(self):
        words = ["python","dog","boy","difficult","apple","monkey"]
        word = random.choice(words)
        message[0]=word
        position = random.randrange(len(word))
        guessWord = word[:position]+"_"+word[(position+1):]
        self.textBrowser.setText(guessWord)

    def GuessJudge(self):
        answer = self.lineEdit.text()
        print(answer)
        message[1]=answer
        print(message)
        if message[0]==message[1]:
            self.textBrowser_2.setText("恭喜你答对了")
        else:
            self.textBrowser_2.setText("很遗憾，答错了")
