一个使用pyqt的word文档查重工具

使用场景

有时我们在借鉴一篇文档之后还不想有太多重复,这个时候可以使用这个工具对两个word文档进行对比

代码

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow, QPushButton, QVBoxLayout, QWidget, QLabel, QFileDialog
from docx import Document
import re, datetime


class WordComparerApp(QMainWindow):
    def __init__(self):
        super().__init__()

        self.initUI()

    def initUI(self):
        self.setWindowTitle('Word 文档比较器')
        self.setGeometry(100, 100, 400, 200)

        self.centralWidget = QWidget(self)
        self.setCentralWidget(self.centralWidget)

        self.layout = QVBoxLayout()

        self.file1_label = QLabel('选择文件1:')
        self.layout.addWidget(self.file1_label)

        self.file1_button = QPushButton('选择文件1')
        self.file1_button.clicked.connect(self.openFile1)
        self.layout.addWidget(self.file1_button)

        self.file2_label = QLabel('选择文件2:')
        self.layout.addWidget(self.file2_label)

        self.file2_button = QPushButton('选择文件2')
        self.file2_button.clicked.connect(self.openFile2)
        self.layout.addWidget(self.file2_button)

        self.compare_button = QPushButton('开始比较')
