Python realizes batch modification of file names

Python3 realizes batch modification of file names for your reference. The specific content is as follows

Take the batch modification of all the picture names in a folder as an example. The annotations are super detailed and the universal template. Readers can draw inferences from one another. Modify the template appropriately, and the effect is remarkable!

# Batch modify file name
# Modify image file names in batch
import os
import re
import sys
def renameall():
 fileList = os.listdir(r"C:\Users\Administrator\Desktop\stars") #To be modified folder
 print("before fixing:"+str(fileList)) #Files contained in the output folder
 currentpath = os.getcwd() #Get the current working directory of the process
 os.chdir(r"C:\Users\Administrator\Desktop\stars") #Modify the current working directory to the location of the folder to be modified
 num=1 #Name variable
 for fileName in fileList: #Traverse all files in the folder
 pat=".+\.(jpg|png|gif)" #Regular expression for matching file names
 pattern = re.findall(pat,fileName) #Make a match
 os.rename(fileName,(str(num)+'.'+pattern[0])) #File rename
 num = num+1 #Change the number and continue to the next item
 print("---------------------------------------------------")
 os.chdir(currentpath) #Change back to the working directory before the program was run
 sys.stdin.flush() #Refresh
 print("After modification:"+str(os.listdir(r"C:\Users\Administrator\Desktop\stars"))) #Output the files contained in the modified folder
renameall()

Run the program:

After modification, the display in the folder:

The modification is successful and we are very satisfied!
