A permissive filename sanitizer.

Project description

A simple, dependency-free, blacklist-based filename sanitizer, for when you want to keep the original filename.

Note that a blacklist based sanitizer will never be as safe as a whitelist based one. In most cases, your best option is to create a safe filename yourself. Your second safest option is to use a whitelist approach (allowing only certain characters). This sanitizer is useful when you want to keep the original filename, including non ascii characters, whenever possible.


pip install sanitize_filename


from sanitize_filename import sanitize

filename = input("Enter a file name:")
filename = sanitize(filename)


> sanitize("A/B/C.txt")

> sanitize("this𓀦filenameḜisあactually...valid.txt")

> sanitize("def.")

> sanitize("NUL")

> sanitize("..")
