It works by opening the input file for reading while ignoring its file type.
We just call that method, and the file is copied. If the source or destination file doesn't exist, we print an error notifying the user that the operation has failed. If the source and destination files are the same, we don't copy them and notify the user of the failed operation.
Python shutil's Different Copy Methods The module shutil has several methods for copying files other than the simple copy method that we have seen above. I'll go over them in some detail here, explaining the differences between them and situations where we might need them.
If you've already opened a file to read from and a file to write to using the built-in open function, then you would use shutil. It is also of interest to use this function when it is necessary to specify the buffer length of the copy operation.
It may help, when copying large files, to increase the buffer length from its default value of 16 KB in order to speed up the copy operation. All of the other copy functions mentioned below call this function at some point.
It is the "base" copy method. We will test an archived file in iso format of 3. We'll be using this function to specify the buffer size:Now, if you want to save this modified content, you just need to extract all the files in the docx, overwrite the content file, and then zip it back up: def _write_and_close_docx (self, xml_content, output_filename): """ Create a temp directory, expand the original docx zip.
AFAIK truncate does not change the inode, but open(, 'w') will create a new inode. But in most cases this does not matter.
I tested it now. Both open(, 'w') and truncate() don't change the inode number of the file. (Tested twice: Once with Ubuntu NFS and once with ext4). By the way, this is not really related to Python. does OS matter when working in python, most important factors getting a new laptop?

I have this code. Python is the latest stable version at the time of writing of tutorial. This Python version is available to download and install.
This article will help you to install Python on Ubuntu and Linuxmint operating system. A python script that renames (moves) files to a destination directory. However it will not overwrite existing files.
The script uses a renaming strategy where a . Confused by python file mode “w+” @NasifImtiazOhi - The Python docs say that w+ will "overwrite the existing file if the file exists".
So as soon as you open a file with w+, it is now an empty file: it contains 0 bytes. If it used to contain data.
