基于PyQt5制作數(shù)據(jù)處理小工具

更新時(shí)間：2022年03月05日 08:35:36 作者：Python 集中營(yíng)

這篇文章主要和大家介紹了如何利用Python中的PyQt5模塊制作一個(gè)數(shù)據(jù)處理小工具，可以實(shí)現(xiàn)根據(jù)每個(gè)Excel數(shù)據(jù)文件里面的Sheet批量將數(shù)據(jù)文件合并成為一個(gè)匯總后的Excel數(shù)據(jù)文件，需要的可以參考一下

需求分析：

現(xiàn)在有一大堆的Excel數(shù)據(jù)文件，需要根據(jù)每個(gè)Excel數(shù)據(jù)文件里面的Sheet批量將數(shù)據(jù)文件合并成為一個(gè)匯總后的Excel數(shù)據(jù)文件。或者是將一個(gè)匯總后的Excel數(shù)據(jù)文件按照Sheet拆分成很多個(gè)Excel數(shù)據(jù)文件。根據(jù)上面的需求，我們先來(lái)進(jìn)行UI界面的布局設(shè)計(jì)。

導(dǎo)入U(xiǎn)I界面設(shè)計(jì)相關(guān)的PyQt5模塊

看一下 UI 界面的功能和布局，感覺(jué)還可以...

下面是布局相關(guān)的代碼塊實(shí)例

    def init_ui(self):
        self.setWindowTitle('Excel數(shù)據(jù)匯總/拆分器  公眾號(hào)：[Python 集中營(yíng)]')
        self.setWindowIcon(QIcon('數(shù)據(jù).ico'))

        self.brower = QTextBrowser()
        self.brower.setReadOnly(True)
        self.brower.setFont(QFont('宋體', 8))
        self.brower.setPlaceholderText('批量數(shù)據(jù)處理進(jìn)度顯示區(qū)域...')
        self.brower.ensureCursorVisible()

        self.excels = QLineEdit()
        self.excels.setReadOnly(True)

        self.excels_btn = QPushButton()
        self.excels_btn.setText('加載批文件')
        self.excels_btn.clicked.connect(self.excels_btn_click)

        self.oprate_type = QLabel()
        self.oprate_type.setText('操作類型')

        self.oprate_combox = QComboBox()
        self.oprate_combox.addItems(['數(shù)據(jù)合并', '數(shù)據(jù)拆分'])

        self.data_type = QLabel()
        self.data_type.setText('合并/拆分')

        self.data_combox = QComboBox()
        self.data_combox.addItems(['按照Sheet拆分'])

        self.new_file_path = QLineEdit()
        self.new_file_path.setReadOnly(True)

        self.new_file_path_btn = QPushButton()
        self.new_file_path_btn.setText('新文件路徑')
        self.new_file_path_btn.clicked.connect(self.new_file_path_btn_click)

        self.thread_ = DataThread(self)
        self.thread_.trigger.connect(self.update_log)
        self.thread_.finished.connect(self.finished)

        self.start_btn = QPushButton()
        self.start_btn.setText('開(kāi)始數(shù)據(jù)匯總/拆分')
        self.start_btn.clicked.connect(self.start_btn_click)

        form = QFormLayout()
        form.addRow(self.excels, self.excels_btn)
        form.addRow(self.oprate_type, self.oprate_combox)
        form.addRow(self.data_type, self.data_combox)

        vbox.addLayout(form)
        vbox.addWidget(self.start_btn)

        hbox = QHBoxLayout()
        hbox.addWidget(self.brower)
        hbox.addLayout(vbox)

        self.setLayout(hbox)

槽函數(shù) update_log，將運(yùn)行過(guò)程通過(guò)文本瀏覽器的方式實(shí)時(shí)展示，方便查看程序的運(yùn)行。

  def update_log(self, text):
        cursor = self.brower.textCursor()
        cursor.movePosition(QTextCursor.End)
        self.brower.append(text)
        self.brower.setTextCursor(cursor)
        self.brower.ensureCursorVisible()

槽函數(shù) excels_btn_click，綁定到文件加載按鈕，處理源文件的加載過(guò)程。

 def excels_btn_click(self):
        paths = QFileDialog.getOpenFileNames(self, '選擇文件', os.getcwd(), 'Excel File(*.xlsx)')
        files = paths[0]
        path_strs = ''
        for file in files:
            path_strs = path_strs + file + ';'
        self.excels.setText(path_strs)
        self.update_log('已經(jīng)完成批文件路徑加載！')

槽函數(shù) new_file_path_btn_click，選擇新文件要保存的路徑。

 def new_file_path_btn_click(self):
        directory = QFileDialog.getExistingDirectory(self, '選擇文件夾', os.getcwd())
        self.new_file_path.setText(directory)

槽函數(shù) start_btn_click，綁定到開(kāi)始按鈕上，使用開(kāi)始按鈕啟動(dòng)子線程工作。

    def start_btn_click(self):
        self.start_btn.setEnabled(False)
        self.thread_.start()

函數(shù) finished，這個(gè)函數(shù)是用來(lái)接收子線程傳過(guò)來(lái)的運(yùn)行完成的信號(hào)，通過(guò)判斷使子線程執(zhí)行完成時(shí)讓開(kāi)始按鈕處于可以點(diǎn)擊的狀態(tài)。

 def finished(self, finished):
        if finished is True:
            self.start_btn.setEnabled(True)

下面是最重要的邏輯處理部分，將所有的邏輯處理相關(guān)的部分全部放到子線程中去執(zhí)行。
