Python is an extensively used in a general-purpose, the high-level programming in the language. Its design is such that the philosophy emphasizes the code of readability. Moreover, its syntax permits the programmers to express their concepts in quite a few lines of the code, then it could be possible in the languages such as Java or C++. This language gives constructs projected to enable or clear the programs on both the sides the large scale and the small scale.
The Python supports a number of programming paradigms, and it includes the functional programming, the imperative and the object-oriented or the procedural styles. It has the features of a dynamic kind of system and an automatic memory management. Moreover, it has a comprehensive and a large standard library.
The interpreters of python are available for the installation on a lot of operating systems, allowing the Python code execution on most of the parts of the systems. By using the third-party tools like the Pyinstaller or the Py2exe, the python code can be packed into a stand-alone executable program for a few of the most liked operating systems. This allows the system of the Python-based software for the use on that environment without the need for the installation of an interpreter in the Python. The CPython is a reference implementation of the Python and if free, open-source software. It also has a community -based development of a model. As nearly all of its alternative implementations are implemented. It is controlled by the Python Software Foundation, which is a non-profit fund. To install a Python is usually easy, and nowadays several UNIX and Linux distributions also include the recent Python. Some of the Windows computers, especially for the HP are coming with the python installed in it. Installation of the Python is unremarkable on most of the platforms. If you want to know that a library with particular functionality or a particular application is existing in the Python then, there is a wide range of possible sources to get the information. The Python offers a Cheese Shop, which is also known as the Python Package Index. It is a reference to the name of the script Monty Python.
It is used in the dynamic typing and the combination of a cycle-detecting of the garbage collector and a reference counting for the memory management. It is an essential characteristic of Python. It is a dynamic name resolution that binds the method and unpredictable names throughout the program execution. The design of it offers only a certain amount of support for the functional programming within the Lisp tradition. This language has a filter, reduce and a map functions. It comprehends the dictionaries, sets and lists as well as the generator expressions. The standard library has two modules such as the functools and the itertools which implements the useful tools borrowed from the Standard ML and the Haskell. The Python is a structure that is fully programmed and is fully supported. There are a number of language features that support the functional program.
|Python 3.8.1 Dec 18, 2019||
Core and Builtins
bpo-39080: Fix the value of end_col_offset for Starred Expression AST nodes when they are among the elements in the args attribute of Call AST nodes.
bpo-39031: When parsing an “elif” node, lineno and col_offset of the node now point to the “elif” keyword and not to its condition, making it consistent with the “if” node. Patch by Lysandros Nikolaou.
bpo-39008: PySys_Audit() now requires Py_ssize_t to be used for size arguments in the format string, regardless of whethen PY_SSIZE_T_CLEAN was defined at include time.
bpo-39022: Update importliib.metadata to include improvements from importlib_metadata 1.3 including better serialization of EntryPoints and improved documentation for custom finders.
bpo-38811: Fix an unhandled exception in pathlib when os.link() is missing. Patch by Toke Høiland-Jørgensen.
bpo-36406: Handle namespace packages in doctest. Patch by Karthikeyan Singaravelan.
bpo-38546: Multiprocessing and concurrent.futures tests now stop
