如何使用目录中的 python any.xlsx 文件重命名？

Question

I could not find similar question here but how can i rename using python any.xlsx file in a directory? The goal is not to hardcode the filename to rename it into something else. Any input or advice is much appreciated. Thank you very much.

What I have tried so far. What it does is, it creates another excel file but i just need the.xlsx in C:\Test to be rename as Master.xlsx.

for root, dirs, files in os.walk("C:\Test", topdown=False,):
for name in files:
    base_name, ext = os.path.splitext(name)  #Split name, extension
    if ext in ".xlsx":
        df = pd.read_excel(os.path.join(root, name))
        df.to_excel(os.path.join(root, 'Master.xlsx'), index=False)

Answer 1

You can find all.xlsx files using the glob module and then rename them using the os module.

To get all the files in a specific folder/directory.

files = glob.glob(directory + '/*.xlsx')

then just loop over it to get the list of files and just rename those files using rename().

os.rename(file, new_name)

full code:

import glob
import os

files = glob.glob('./' + '/*.xlsx')

for file in files:
    os.rename(file, file.replace('.xlsx', '_new.xlsx'))

Use OS client for python

import os
os.chdir("C:\Test") #if you are running your code in 'c:\' location you need to do this so that your code will run inside test folder.
for file in os.listdir():
    if file.endswith(".xlsx"):
        os.rename(file, "new_name.xlsx")
