Python 3 – os.renames() Method
In Python, the os.renames()
method is used to recursively rename directories or files. This method is similar to the os.rename()
method, but it can be used to perform a bulk renaming operation on directories and their contents.
The syntax for using os.renames()
is:
os.renames(src, dst)
Here, the src
parameter represents the source file or directory, while dst
represents the destination file or directory (which may or may not exist). The method recursively renames the contents of src
and all its subdirectories, if any, to dst
.
Let’s take a look at a sample code to understand how os.renames()
works:
import os
src = "/path/to/source/dir" # path to source directory
dst = "/path/to/destination/dir" # path to destination directory
os.renames(src, dst)
In the above code, we have imported the os
module and then used the os.renames()
method to rename the source directory to the destination directory.
By default, the os.renames()
method will raise an exception if dst
already exists. However, you can override this behavior by setting the src_dir_fd
and dst_dir_fd
parameters, which allow you to specify file descriptors for the source and destination directories, respectively. Here’s an example:
import os
src = "/path/to/source/dir" # path to source directory
dst = "/path/to/destination/dir" # path to destination directory
src_fd = os.open(src, os.O_RDONLY) # file descriptor for source directory
dst_fd = os.open(dst, os.O_WRONLY) # file descriptor for destination directory
os.renames(src, dst, src_dir_fd=src_fd, dst_dir_fd=dst_fd)
Here, we have opened the source and destination directories using the os.open()
method to obtain their file descriptors. We then pass these file descriptors to the os.renames()
method using the src_dir_fd
and dst_dir_fd
parameters.
You can also use the os.renames()
method to move files or directories to a different location on the same filesystem by providing different paths for the source and destination directories. Here’s an example:
import os
src = "/path/to/source/file.txt" # path to source file
dst = "/path/to/destination/newname.txt" # path to destination file
os.renames(src, dst)
In this case, we have used os.renames()
to rename the source file to a new name and move it to a different location on the same filesystem.
Conclusion
The os.renames()
method is a powerful tool for performing bulk renaming and file move operations on your filesystem. By understanding its syntax and parameters, you can use it to efficiently manage your files and directories in Python.
