replace_file_extension()

audeer.replace_file_extension(path, new_extension, *, ext=None)

If ext is not None but path ends on a different extension, the original path is returned.

Parameters

• path (Union[str, bytes]) – path to file

• new_extension (str) – new file extension

• ext (Optional[str]) – explicit extension to be removed

Return type

str

Returns

path to file with a possibly new extension

'file'
>>> replace_file_extension("file.tar.gz", "zip", ext="tar.gz")
