非常抱歉，下面是更新后的代码，按照Python的格式进行编写：import sys
from PySide6.QtWidgets import QApplication, QMainWindow, QPushButton, QVBoxLayout, QWidget, QFileDialog
from openpyxl import Workbook, load_workbook
class ExcelComparator(QMainWindow):
def __init__(self):
super().__init__()
self.setWindowTitle("Excel Comparator")
self.main_widget = QWidget()
self.setCentralWidget(self.main_widget)
layout = QVBoxLayout(self.main_widget)
# Button to start comparison
self.compare_button = QPushButton("开始比较")
self.compare_button.clicked.connect(self.compare_and_save)
layout.addWidget(self.compare_button)
def crawl_data(self, url):
# Function to crawl data from a webpage and save it to Excel
response = requests.get(url)
# Here you should parse the response content and extract the data
# For demonstration, let's assume we have the data in a list of tuples
data = [...]
# Create a new workbook
wb = Workbook()
ws = wb.active
# Write data to worksheet
for row in range(len(data)):
for col in range(len(data)):
ws.cell(row=row+1, column=col+1, value=data[row][col])
# Save workbook to Excel file
wb.save("web_data.xlsx")
def read_sql_data(self):
# Function to read data from SQL and save it to Excel
# Here you should write code to connect to your SQL database and retrieve data
# For demonstration, let's assume we have the data in a list of tuples
data = [...]
# Create a new workbook
wb = Workbook()
ws = wb.active
# Write data to worksheet
for row in range(len(data)):
for col in range(len(data)):
ws.cell(row=row+1, column=col+1, value=data[row][col])
# Save workbook to Excel file
wb.save("sql_data.xlsx")
def compare_and_save(self):
# Function to compare data from Excel sheets and save the differences
# Load data from Excel sheets
web_wb = load_workbook("web_data.xlsx")
sql_wb = load_workbook("sql_data.xlsx")
web_ws = web_wb.active
sql_ws = sql_wb.active
# Find rows in sql_ws that are not present in web_ws
diff_rows = []
for row in sql_ws.iter_rows(min_row=2):
match = False
for compare_row in web_ws.iter_rows(min_row=2):
if all(cell.value == compare_cell.value for cell, compare_cell in zip(row, compare_row)):
match = True
break
if not match:
diff_rows.append([cell.value for cell in row])
# Create a new workbook for the differences
diff_wb = Workbook()
diff_ws = diff_wb.active
# Write differences to worksheet
for row in range(len(diff_rows)):
for col in range(len(diff_rows[row])):
diff_ws.cell(row=row+1, column=col+1, value=diff_rows[row][col])
# Save workbook with differences to Excel file
diff_wb.save("comparison_result.xlsx")
if __name__ == "__main__":
app = QApplication(sys.argv)
window = ExcelComparator()
window.show()
sys.exit(app.exec())
