Prerequisite: OS module in Python.
os.replace() method in Python is used to rename the file or directory. If destination is a directory, OSError will be raised. If the destination exists and is a file, it will be replaced without error if the action performing user has permission. This method may fail if the source and destination are on different filesystems.
Syntax: os.replace(source, destination, *, src_dir_fd=None, dst_dir_fd=None2)
Parameter:
- source: Name of file or directory which we want to rename.
- destination: Name which we want to give in destination.
- src_dir_id : This parameter stores the source directory’s or file,
file descriptor referring to a directory.- dst_dir_fd: It is a file descriptor referring to a directory,
and the path to operate. It should be relative,
path will then be relative to that directory. If
the path is absolute, dir_fd is ignored.Return Type: This method does not return any value.
Code #1: Use of os.replace() method to rename a file.
Python3
# Python program to explain os.replace() method # importing os module import os # file name file = "f.txt" # File location which to rename location = "d.txt" # Path path = os.replace( file , location) # renamed the file f.txt to d.txt print ( "File %s is renamed successfully" % file ) |
Output:
File f.txt is renamed successfully
Code #2: Handling possible errors. (If necessary permissions are given then output will be as shown in below)
Python
# Python program to explain os.replace() method # importing os module import os # Source file path source = './file.txt' # destination file path dest = './da' # try renaming the source path # to destination path # using os.rename() method try : os.replace(source, dest) print ( "Source path renamed to destination path successfully." ) # If Source is a file # but destination is a directory except IsADirectoryError: print ( "Source is a file but destination is a directory." ) # If source is a directory # but destination is a file except NotADirectoryError: print ( "Source is a directory but destination is a file." ) # For permission related errors except PermissionError: print ( "Operation not permitted." ) # For other errors except OSError as error: |
Output:
Source is a file but destination is a directory.
