Question

文件夹中有很多CSV文件，我希望将其重命名。有一个Excel工作表，其中包含要重命名为文件夹的文件的名称。

文件夹中的文件命名为

TestData_30April.csv
TestData_20April.csv
TestData_18April.csv etc

而Excel工作表中的名称为

0.25-TestData_30April
0.98-TestData_20April
0.33-TestData_20April etc

Excel工作表中的第一行还包含标头名称，而病房中的第二行包含要重命名的文件名。

我的目标是重命名

对于所有其他文件，也从

TestData_30April.csv到0.25-TestData_30April.csv。

以下是代码：

import os
import xlrd

#Excel Sheet containing name of files to be renamed in that folder
path="C:\\Users\\Desktop\\Test_Data\\Test_Summary.csv"

#Folder Containg all orginal file names
dir = "C:\\Users\\Desktop\\Wear_Data"

wb = xlrd.open_workbook(path) 
sheet = wb.sheet_by_index(0)
sheet.cell_value(0, 0)

#In excel sheet column X or col_values(23) contains the file name to be renamed
print(sheet.col_values(23))  

list_of_filename_in_folder = [] # name of the files in the folder
list_of_filename_in_excel = [] #name of the files in excel
path_to_folder = ''  # base path of folder  
for name in list_of_filename_in_excel:
    excel_file_name = os.path.join(path_to_folder, name,'.csv')
    dir_file_name = os.path.join(path_to_folder,name.split('-')[1],'.csv' )
    if os.path.exists(dir_file_name):
        print('changing file name {} to {}'.format(name.split('-')[1],name))
        os.rename(dir_file_name, excel_file_name)
    else:
        print('no file {} with name found in location'.format(name.split('-')[1]+'.csv')








Here is the error
    dir_file_name = os.path.join(path_to_folder,name.split('-')[1],'.csv')

IndexError: list index out of range

尝试以下代码：

for name in list_of_filename_in_excel:
    excel_file_name = os.path.join(path_to_folder, name,'.csv')
    newname = name
    if '-' in name:
        newname = name.split('-')[1]
    dir_file_name = os.path.join(path_to_folder,newname,'.csv' )

    if os.path.exists(dir_file_name):
        print('changing file name {} to {}'.format(newname,name))
        os.rename(dir_file_name, excel_file_name)
    else:
        print('no file {} with name found in location'.format(newname+'.csv')

使用Excel工作表中的名称映射，借助Python Script重命名文件夹中文件的名称
