It supports added to the archive, compiling if necessary. This class is pretty similar to ZipFile, and its especially handy when you need to bundle Python modules and packages into ZIP files. The main difference from ZipFile is that the initializer of PyZipFile takes an optional argument called optimize, which allows you to optimize the Python code by compiling it to bytecode before archiving it. ignored otherwise. Its important to keep in mind that you need to know beforehand the character encoding format of any member file that you want to process using .decode(). The names in this list are valid arguments to, Allows compression and decompression using the, Provides an interface for compressing and decompressing data using the Bzip2 compression algorithm, Provides classes and functions for compressing and decompressing data using the LZMA compression algorithm.

This is meant for For example, the current data decryption feature can be pretty slow because it uses pure Python code. Packaging the .pyc file rather than the .py file makes the importing process way more efficient because it skips the compilation step. If the file size is known in advance, The get_file_from_stream() function is a generator function simulating a stream of files to process. The output of above program may look like this: Here, infolist() method creates an instance of ZipInfo class which contains all the information about the zip file.We can access all information like last modification date of files, file names, system on which files were created, Zip version, size of files in compressed and uncompressed form, etc. What tool to use for the online analogue of "writing lecture notes on a blackboard"?
