Python 如何使用openpyxl返回列中的第一个和最后一个值，并将excel文件的标题更改为它们？

我试图更改五个文件的标题，以显示该文件中由“\u1”分隔的列中的第一个和最后一个值

例如，在一列中，如果我有值0001000200030004，我希望找到第一个和最后一个值，并将文件标题更改为0001_0004

files=os.listdir(os.getcwd())
for file in files:
if file.endswith('.xlsx'):
    print(file)
    try: 
        wb=openpyxl.load_workbook(os.path.join(os.getcwd(),file))
        print('reading workbook'+file)
        ws=wb['Sheet1'] 
        for row in range(7, ws.max_row+1):
            cell = ws.cell(row = row, column = 7)
            #code to change name
            wb.save(os.path.join(os.getcwd(),file))
        print('file title changed') 
    except Exception as e:
        print(e)

这只是我能想到的一个快速解决方案，它不是最佳解决方案，您可以调整它以更快地获得所需的结果

希望这有帮助

path = os.getcwd()
files = os.listdir(os.getcwd())
for filename in files:
    if filename.endswith('.xlsx'):
        print(filename)
        wb = openpyxl.load_workbook(os.path.join(os.getcwd(),filename), data_only = True)
        ws = wb['Sheet1']
        final = ws.max_row
        original_file = str(filename)
        cell = ws['G7'].value
        filenamep1 = cell
        cell = ws.cell(row = final, column = 7).value
        filenamep2 = cell
        os.rename(original_file, path + '\\' + filenamep1 + '_' + filenamep2 + '_' + 
        original_file)
print("All files renamed")

这就是我最后用来重命名文件的内容

，您的代码遇到了什么问题？我找不到任何可以让我在列的第一行和最后一行找到单元格值的内容。这有助于我达到目标

path = os.getcwd()
files = os.listdir(os.getcwd())
for filename in files:
    if filename.endswith('.xlsx'):
        print(filename)
        wb = openpyxl.load_workbook(os.path.join(os.getcwd(),filename), data_only = True)
        ws = wb['Sheet1']
        final = ws.max_row
        original_file = str(filename)
        cell = ws['G7'].value
        filenamep1 = cell
        cell = ws.cell(row = final, column = 7).value
        filenamep2 = cell
        os.rename(original_file, path + '\\' + filenamep1 + '_' + filenamep2 + '_' + 
        original_file)
print("All files renamed")
