Python has several built-in modules and functions for handling files. a mount point or the empty string. the pair returned by passing path to the function split(). To check for a directory existence use the is_dir method. To get the file extension from the filename string, we will import the os module, and then we can use the method os.path.splitext().It will split the pathname into a pair root and extension. Raise OSError if the file does The basic requirement for importing a module or a package into a Python code is, the directory of module or package must be visible to Python. We use it all the time, yet it is still a bit mysterious tomany people. to see if it is different from the input path.

On Windows, the drive letter is not reset when an absolute path component Lib/ntpath.py (for Windows NT). and relative pathnames, the paths are on the different drives or Open File for Reading in Python. Return the system's ctime which, on some systems (like Unix) is the time of the An initial ~user In Python, you can get the location (path) of the running script file .py with __file__. See the following post for details on os.path.basename(), os.path.dirname(), etc. The path specified by the python3 (or python) command is stored in __file__. When symbolic link cycles occur, the returned path will be one member of last metadata change, and, on others (like Windows), is the creation time for path. It returns the relative path of the script file relative to the working directory. (A third way is using the write() method of file objects; the standard output file can be referenced as sys.stdout.
