Database and storage modules connect Python applications to various data persistence systems. These libraries support both traditional SQL databases and modern NoSQL solutions, providing interfaces for data storage and retrieval. SQLAlchemy dominates the SQL space, while specialized drivers enable NoSQL da...
The gzip module provides a class, GzipFile, that can be used to read and write files compatible with the GNU gzip program. GzipFile objects work like ordinary files except that data is automatically compressed or decompressed. shutil The shutil module is used to perform high-level file operatio...

Python虚拟机还会将已经 import 过的 module 缓存起来,放到一个全局 module 集合 sys.modules 中。这样做有一个好处,即如果程序的在另一个地方再次 import 这个模块,Python 虚拟机只需要将全局 module 集合中缓存的那个 module 对象返回即可。 你现在一定想到了 sys.modules 是一个 dict 对象,可以通过 type(sys.m...
5. New modules and libraries: Python 3.9 introduces several new modules and updates existing libraries. One notable addition is the `zoneinfo` module, which provides an improved interface for working with time zones. The `abc` module has also been enhanced with new features, making it easier ...
'Topic :: Software Development :: Libraries :: Python Modules', 'Intended Audience :: Developers', ], ) 首先,导入setuptools。这是一个非常有用代码包,可轻松对Python包进行发行,即使它不包括在标准库中(类似的distutils是比不了的),它仍然是当今Python包发行的标准,应该牢记于心。本文只使用了setuptools包...
Last year, we did a recap with what we thought were the best Python libraries of 2015, which was widely shared within the Python community (see post in r/Python). A year has gone by, and again it is time to give due credit for the awesome work that has been done by the open sour...
无法舍弃GIL的原因主要在于:在GIL和CPython的已经开发了大量的features、libraries和packages。如果舍弃GIL,就意味着一切都要推倒重来,这个工程太大了。 6. GIL对哪些程序影响较小? 既然如此,是不是创建多线程已经没有意义了呢?还是先看看官方文档: Luckily, many potentially blocking or long-running operations, suc...
In addition to those standard library modules, we also covered several excellent libraries that are also available to you on the PyPI. You’ve seen how:flit makes it easy for you to create your own Python packages, and submit them to the PyPI. libraries like colorama and begins improve ...
