3. Batch modify the image name

Write a function to batch file names , It should be noted that we only deal with a certain file type , such as .jpeg file .

therefore , We need to Pass two parameters filePostFix and rootdir,filePostFix Indicates the file suffix that needs to be modified ,rootdir Indicates the path to traverse the file .

To achieve selective selection of files , The core code is if i[-len(filePostFix):] == filePostFix: , Indicates that only the selected suffix file name is modified .

The default modified file name here is an incrementing number + Form of file suffix .

Use os Provided rename Method to change the name ,os.rename(oldname, newname).

def renameFiles(rootdir="./", filePostFix=".jpeg"):
    # Get all the files in this directory , Put it in the list 
    fileList = os.listdir(rootdir)
    index = 0
    for i in fileList:
        if i[-len(filePostFix):] == filePostFix:
            #  Get old file name （ Is the path + file name ）
            oldname = rootdir + os.sep + fileList[index]   # os.sep Add system separator 
            #  Set a new file name 
            newname = rootdir + os.sep + str(index) + filePostFix
            os.rename(oldname, newname)   #  use os Module rename Method to rename the file 
            
            index += 1
