4.6. Check a filename

is_valid_filename() function returns True if a filename is valid for a specified platform.

Sample Code:

from pathvalidate import is_valid_filename, sanitize_filename

fname = "fi:l*e/p\"a?t>h|.t<xt"
print(f"is_valid_filename('{fname}') return {is_valid_filename(fname)}\n")

sanitized_fname = sanitize_filename(fname)
print(f"is_valid_filename('{sanitized_fname}') return {is_valid_filename(sanitized_fname)}\n")

Output:

is_valid_filename('fi:l*e/p"a?t>h|.t<xt') return False

is_valid_filename('filepath.txt') return True

4.7. Check a filepath

is_valid_filepath() function returns True if a filepath is valid for a specified platform.

Sample Code:

from pathvalidate import is_valid_filepath, sanitize_filepath

fpath = "fi:l*e/p\"a?t>h|.t<xt"
print(f"is_valid_filepath('{fpath}') return {is_valid_filepath(fpath)}\n")

sanitized_fpath = sanitize_filepath(fpath)
print(f"is_valid_filepath('{sanitized_fpath}') return {is_valid_filepath(sanitized_fpath)}\n")

Output:

is_valid_filepath('fi:l*e/p"a?t>h|.t<xt') return False

is_valid_filepath('file/path.txt') return True
