This code adds a Python file called get_zip_sum.py to a ZIP archive called PyZipFile.zip. If the ZIP archive already exists, it will be overwritten. If the ZIP archive does not exist, it will be created.
As previously mentioned, ZIP archives can contain multiple files and folders. However, the default ZIP structure places two folders at the top of the archive: the “.” folder (which contains the archive’s central directory information) and the “.PKL” folder (which contains the archive’s file entries or “contents”). The “.
Besides the just-created ZIP archive and the Python file, the code also creates a folder called PyZipFile.zip (and if necessary, a folder called PyZipFile.zip.1). Why is this done?
Because.py files are usually scripts that contain conditional statements and other logical statements. As such, when a.py file is run, it is executed line by line until it comes across a conditional statement, in which case it is compiled to byte code. This way, if the conditional statement is not satisfied, the byte code is not generated, thus saving time and computing resources.
Windows PowerShell provides several cmdlets that help you work with Zip archives. They can be used to perform any operation you might want to perform on ZIP archives, including writing files, extracting, deleting, etc.
A ZIP archive is a file, so it can be sent via e-mail or posted as part of an HTML e-mail. In addition, files stored in the ZIP archive can be compressed as part of the same message. This way, you can send a message with more ZIP files than can fit in a single message in the tag.
You can also add a list of files to a ZIP archive using a for loop. However, if you do so, you must add all the files to the archive, even if some of them are already in the archive. To avoid that, you must add only the file that you are going to add to the archive. To do that, you can use the zip_file.namelist() method, which returns a list of filenames for the ZIP archive. You can also test if the file is already in the archive to avoid adding it again.
Notice that you can obtain the file name from the basename and the extension of the filename. You can obtain the full filename from that using the os.path.splitext() function. To add a file to an archive, you can use the write() method of the ZipFile object, passing the filename and the full path of the file. 827ec27edc
