How to name files with a count when saving?

Question

I am saving images with count function like below

count = 0
new_im.save("C:/Users/"+str(count)+".jpg", "JPEG", quality=100, optimize=True, progressive=True)
count += 1

The images' names will be 1.jpg, 2.jpg, 3.jpg, etc.

How to make it save as 001.jpg, 002.jpg, 003.jpg?

Answer 1

count = 0
new_im.save("C:/Users/"+'{:0>3}'.format(count)+".jpg", "JPEG", quality=100, optimize=True, progressive=True)
count += 1

I have chosen the above so that it looks as similar to your code as possible. But as Gino Mempin has pointed out in the comments there are nicer ways to write it. He suggested

"C:/Users/{:0>3}.jpg".format(count)

I think I would even prefer using f strings like so:

f"C:/Users/{count:0>3}.jpg"
