How to rename all the files in a folder in numeric order?

The folder "Photos" has more than 800 images in it. I want to rename all of them in numeric order, starting with 1.

All I could get is the below code. It looks right to me but it doesn't work. I get an error on the rename:

TypeError: coercing to Unicode: need string or buffer, int found

Code:

import os

x = 0

for i in os.listdir("E:\\Photos"): 
    if  i.endswith(".jpg"):
        os.rename(i, x)
        x+=1

import os
folderPath = r'E:\Photos'
fileSequence = 1

for filename in os.listdir(folderPath):
    os.rename(filename, 'image_' + str(fileSequence)+".JPG")
    fileSequence +=1

If you want to name it like image_1 , image_2 etc.. then you can use the above portion otherwise remove image_ from the above code. The rest will work perfectly fine.

There is a way to do this in PowerShell that has been answered here:

As a quick note:

$count = 1
Get-ChildItem -Path '.' -File | Rename-Item -NewName { '{0:D4}.png' -f $script:count++ }

As mentioned in the other answer, the os.rename function won't accept an integer.

I'm sure there's a more pythonic way to write this but here's an answer based solely on your code:

#! /usr/bin/python3.4
    import os

    x = 0
    photo_dir=os.path.dirname(__file__)+"\\photos\\"
    extension = ".jpg"
    for i in os.listdir(photo_dir): 
        if  i.endswith(extension):
            os.rename(photo_dir+i, photo_dir+str(x)+extension)
            x+=1

rename takes two strings; you gave it an integer. Try something like this:

os.rename(i, str(x))

or even a descriptive name, of this form:

os.rename(i, "photo" + str(x) + ".jpg")

If you want three-digit numbering (i.e. "photo001.jpg" instead of "photo1.jpg"), then check out the <string>.format method.
