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
import os
file = "f.txt"
location = "d.txt"
path = os.replace(file, location)
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
import os
source = './file.txt'
dest = './da'
try:
os.replace(source, dest)
print("Source path renamed to destination path successfully.")
except IsADirectoryError:
print("Source is a file but destination is a directory.")
except NotADirectoryError:
print("Source is a directory but destination is a file.")
except PermissionError:
print("Operation not permitted.")
except OSError as error:
|
Output:
Source is a file but destination is a directory.
