Python Wget: Check for duplicate files and skip if it exsists?

So I'm downloading files with WGET and I want to check if the file exsists before I download it. I know with the CLI version it has an option to: (see example).

# check if file exsists
# if not, download
wget.download(url, path)

With WGET it downloads the file without needing to name it. This is important because I don't want to rename the files when they already have a name.

If there is an alternative file downloading method that allows for checking for exsisting files please tell me! Thanks!!!
