python copy file and rename with code examples

Python provides several ways to copy and rename a file. One way is to use the built-in shutil module, which has methods for copying and renaming files. Another way is to use the os module, which also provides methods for working with files.

Here is an example of using the shutil module to copy and rename a file:

import shutil

# original file
src_file = 'original.txt'

# new file name
dst_file = 'copy.txt'

# copy the file
shutil.copy(src_file, dst_file)

#rename the file
shutil.move(dst_file, 'renamed.txt')

In this example, the shutil.copy() method is used to copy the file original.txt to a new file named copy.txt. Then, the shutil.move() method is used to rename the file to renamed.txt.

Another way to copy and rename a file is to use the os module. Here is an example of how to do this:

import os

# original file
src_file = 'original.txt'

# new file name
dst_file = 'copy.txt'

# copy the file
os.system('cp ' + src_file + ' ' + dst_file)

#rename the file
os.rename(dst_file, 'renamed.txt')

In this example, the os.system() method is used to run the cp command to copy the file original.txt to a new file named copy.txt. Then, the os.rename() method is used to rename the file to renamed.txt.

Another way is to use the standard open function to copy the contents of the file and then use the os.rename function to rename the new file.

import os

# original file
src_file = 'original.txt'

# new file name
dst_file = 'renamed.txt'

# copy the content
with open(src_file, 'r') as src, open(dst_file, 'w') as dst:
    dst.write(src.read())

#rename the file
os.rename(dst_file, 'renamed.txt')

There are many ways to copy and rename a file in Python, and the best method for your application will depend on your specific requirements. The above examples show three different ways to accomplish this task, but it's important to choose the one that best suits your needs.

In addition to copying and renaming files, the shutil and os modules also provide other useful functions for working with files and directories.

The shutil module provides several functions for creating, moving, and deleting directories. For example, the shutil.rmtree() function can be used to delete a directory and all its contents, while the shutil.mkdir() function can be used to create a new directory. Additionally, the shutil.copytree() function can be used to recursively copy an entire directory and its contents to a new location.

The os module also provides several functions for working with directories. For example, the os.makedirs() function can be used to create a new directory, while the os.rmdir() function can be used to delete an empty directory. The os.listdir() function can be used to get a list of all the files and directories in a given directory.

Another useful function provided by the os module is os.path.join(), which can be used to join multiple path components into a single path. This is useful when working with file paths, as it ensures that the correct path separator is used for the current operating system.

In addition to working with directories, the os module also provides several functions for working with file attributes, such as file permissions, timestamps, and ownership. For example, the os.chmod() function can be used to change the permissions of a file, while the os.utime() function can be used to change the timestamps of a file.

Another useful function provided by the os module is os.path.exists(), which can be used to check if a file or directory exists. This function returns True if the file or directory exists, and False otherwise.

In summary, the shutil and os modules provide many useful functions for working with files and directories in Python. These functions can be used to perform common tasks such as copying, renaming, and deleting files and directories, as well as working with file attributes and directories.
