基於PyQt5制作數據處理小工具
需求分析:
現在有一大堆的Excel數據文件,需要根據每個Excel數據文件裡面的Sheet批量將數據文件合並成為一個匯總後的Excel數據文件。或者是將一個匯總後的Excel數據文件按照Sheet拆分成很多個Excel數據文件。根據上面的需求,我們先來進行UI界面的佈局設計。
導入UI界面設計相關的PyQt5模塊
from PyQt5.QtWidgets import * from PyQt5.QtCore import * from PyQt5.QtGui import *
應用操作相關的模塊
import sys import os
excel 數據處理模塊
import openpyxl as pxl import pandas as pd
看一下 UI 界面的功能和佈局,感覺還可以…
下面是佈局相關的代碼塊實例
def init_ui(self): self.setWindowTitle('Excel數據匯總/拆分器 公眾號:[Python 集中營]') self.setWindowIcon(QIcon('數據.ico')) self.brower = QTextBrowser() self.brower.setReadOnly(True) self.brower.setFont(QFont('宋體', 8)) self.brower.setPlaceholderText('批量數據處理進度顯示區域...') 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(['數據合並', '數據拆分']) self.data_type = QLabel() self.data_type.setText('合並/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('開始數據匯總/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) form.addRow(self.new_file_path, self.new_file_path_btn) vbox = QVBoxLayout() vbox.addLayout(form) vbox.addWidget(self.start_btn) hbox = QHBoxLayout() hbox.addWidget(self.brower) hbox.addLayout(vbox) self.setLayout(hbox)
槽函數 update_log,將運行過程通過文本瀏覽器的方式實時展示,方便查看程序的運行。
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 excels_btn_click,綁定到文件加載按鈕,處理源文件的加載過程。
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('已經完成批文件路徑加載!')
槽函數 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 start_btn_click,綁定到開始按鈕上,使用開始按鈕啟動子線程工作。
def start_btn_click(self): self.start_btn.setEnabled(False) self.thread_.start()
函數 finished,這個函數是用來接收子線程傳過來的運行完成的信號,通過判斷使子線程執行完成時讓開始按鈕處於可以點擊的狀態。
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的部分全部放到子線程中去執行。
class DataThread(QThread): trigger = pyqtSignal(str) finished = pyqtSignal(bool) def __init__(self, parent=None): super(DataThread, self).__init__(parent) self.parent = parent self.working = True def __del__(self): self.working = False self.wait() def run(self): self.trigger.emit('啟動批量處理子線程...') oprate_type = self.parent.oprate_combox.currentText().strip() data_type = self.parent.data_combox.currentText().strip() files = self.parent.excels.text().strip() new_file_path = self.parent.new_file_path.text() if data_type == '按照Sheet拆分' and oprate_type == '數據合並': self.merge_data(files=files, new_file_path=new_file_path) elif data_type == '按照Sheet拆分' and oprate_type == '數據拆分': self.split_data(files=files, new_file_path=new_file_path) else: pass self.trigger.emit('數據處理完成...') self.finished.emit(True) def merge_data(self, files, new_file_path): num = 1 new_file = new_file_path + '/數據匯總.xlsx' writer = pd.ExcelWriter(new_file) for file in files.split(';'): if file.strip() != '': web_sheet = pxl.load_workbook(file) sheets = web_sheet.sheetnames for sheet in sheets: sheet_name = sheet.title() self.trigger.emit('準備處理工作表名稱:' + str(sheet.title())) data_frame = pd.read_excel(file, sheet_name=sheet_name) sheet_name = sheet_name + 'TO數據合並' + str(num) data_frame.to_excel(writer, sheet_name, index=False) num = num + 1 else: self.trigger.emit('當前路徑為空,繼續...') writer.save() writer.close() def split_data(self, files, new_file_path): num = 1 for file in files.split(';'): if file.strip() != '': web_sheet = pxl.load_workbook(file) sheets = web_sheet.sheetnames for sheet in sheets: sheet_name = sheet.title() self.trigger.emit('準備處理工作表名稱:' + str(sheet.title())) data_frame = pd.read_excel(file, sheet_name=sheet_name) writer = pd.ExcelWriter(new_file_path + '/數據拆分' + str(num) + '.xlsx') data_frame.to_excel(writer, '數據拆分', index=False) writer.save() writer.close() num = num + 1 else: self.trigger.emit('當前路徑為空,繼續...')
上面就是主要的代碼塊實現過程,有需要的可以參考一下。歡迎大佬在評論區進行留言。
搞瞭一個程序運行效果圖,看一下執行效果。
