如何使用 openpyxl return 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?

How to return first and last values in a column using openpyxl and change the title of the excel file to them?

我正在尝试更改五个文件的标题,以在该文件的列中显示第一个和最后一个值,并用“_”分隔

例如,在一列中,如果我有值 0001,0002,0003,0004,我想找到第一个和最后一个值并将文件的标题更改为 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)
files=os.listdir(os.getcwd())
all_xls = []
for f in files:
   if f.endswith('.xlsx'):
       all_xls.append(f.replace('.xls', '')

all_xls.sort()
first_file = all_xls[0]
last_file = all_xls[-1]
#Do your renaming using os.rename('src', 'dest')

这只是我能想到的一个快速解决方案,并不是最佳解决方案,您可以对其进行调整以更快地获得所需结果。

希望这对您有所帮助。

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")

这就是我最终用来重命名文件的内容
