Have you been struggling with zip file handling in Python 2.7? Are you curious about the new features introduced in Python 3.9 but don’t want to abandon your legacy codebase? Look no further! Zipfile39 is here to empower your Python 2.7 projects and bring the latest zip file capabilities to your fingertips.
Zipfile39: Backporting Python 3.9 to Python 2.7
Zipfile39 is a backport of the zip file module from Python 3.9 to older Python versions, including Python 2.7. This means that you can utilize the zf.open(name, 'w') method even in your legacy projects. Say goodbye to compatibility issues and embrace the power of modern Python zip file handling.
Enhanced Compression Methods
One of the key advantages of Zipfile39 is the introduction of new compression methods for zip files. With Zipfile39, you gain access to the following compression handlers:
- ZIP_DEFLATED64 (method 9)
- ZIP_DCLIMPLODED (method 10)
- ZIP_ZSTANDARD (method 93)
- ZIP_XZ (method 95)
- ZIP_PPMD (method 98)
The ZIPZSTANDARD handler in Python 2.7 utilizes zstandard 0.14.1, offering enhanced compression capabilities. Moreover, the ZIPDEFLATED handler benefits from acceleration when the isal package is installed, providing faster crc32 and inflation processes.
Optional Requisites: Unlocking Additional Features
To further enhance your zip file operations in Python 2.7, Zipfile39 offers a range of optional requisites that unlock additional features and capabilities. Let’s take a look at some of these requisites and their advantages:
-
backports.lzma: Enables the use of ZIP_LZMA (method 14) Python 2 handler, expanding your compression options even further.
-
dclimplode: Provides support for ZIP_DCLIMPLODED (method 10), allowing you to utilize this compression method in your zip files.
-
zstandard or pyzstd: If you’re running Python 3, you can leverage the ZIP_ZSTANDARD handler with the zstandard or pyzstd packages. These packages offer improved compression ratios and faster decompression speeds.
-
isal: Installing the isal package unlocks accelerated crc32 and inflation processes for the ZIP_DEFLATED compression method. Additionally, you gain access to four additional compression levels (-10, -11, -12, and -13) that correspond to isal’s compression levels 0, 1, 2, and 3.
-
slz: The slz package enables the ZIP_DEFLATED compresslevel -21, providing even more fine-grained control over the compression process.
-
codecs7z: With the codecs7z package, you can enjoy 7-zip’s ultimate compression levels (compresslevel 11 to 19) for ZIPDEFLATED and ZIPBZIP2 compression methods.
-
pyppmd: If you’re running Python 2.7, you can utilize the pyppmd package to enable the ZIP_PPMD handler. This package offers efficient PPMd compression, expanding your compression options.
-
zipfiledeflate64 or inflate64: Installing the zipfiledeflate64 package (or inflate64, if using Python 3) enables the use of the ZIP_DEFLATED64 compression method.
Conclusion
With Zipfile39, you can breathe new life into your Python 2.7 projects and take advantage of the latest zip file capabilities introduced in Python 3.9. By backporting Python 3.9 functionality to Python 2.7 and offering additional compression methods, Zipfile39 empowers you to enhance your zip file operations and improve compression efficiency.
Whether you’re looking to accelerate crc32 and inflation, explore new compression methods, or unlock advanced compression levels, Zipfile39 provides the necessary tools and requisites to accomplish your goals. Say goodbye to compatibility constraints and embrace the future of zip file handling in legacy Python.
Give Zipfile39 a try today and experience the power of modern zip file operations in Python 2.7!
Keep coding, keep exploring, and keep pushing the boundaries of what’s possible.
