Answer 1

Using the path module , you'd have to check if the existing path exists.

So checking if the image exists, you'd check

# Check if the base path exists
save_path = "pic.jpg"

# Check if it exists and otherwise modify path
i = 2
while path.exists(save_path):
    save_path + "(" + i + ")"
    i += 1

# Write your file here

The same process you can use for the folders.
