If you are stuck on legacy Python, there is also a backport available for Python 2. About Mkyong.com. Below is the code example, each method comments tells it’s function. ''' Rename this file or directory to the given target, and return a new Path instance pointing to target. To do it, you can use the exists() function from the os.path module or is_file() method from the Path class in the pathlib module. Pure path objects provide path-handling operations which don’t actually access a filesystem. 2) Let s be a std:: filesystem:: file_status determined as if by status (p) or status (p, ec) (symlinks are followed), respectively.
