Faster CPython is Here to Make Python 3.11 Smart and Powerful

Written in C and Python, CPython is the default and most widely used implementation of the Python language.

Python is one of the most popular programming languages and it is incredibly easy to learn and use for beginners and newcomers in the industry. The language is the most accessible among all the programming languages available because it has simplified syntax that is not complicated at all and gives more emphasis on natural language. Due to its ease of learning and usage, Python codes can easily be written and executed much faster than other programming languages. One of the main reasons why Python's popularity has exponentially grown is due to its simplicity in syntax so that it could be easy to read and developed by amateur professionals as well. The Python programming language delivers new amazing versions once a year, along with a feature-locked beta release in the previous half of the year, and the concluding release comes up at the end of the year. The feature finalized set for Python 3.11 has been finalized just now only, with a beta version reachable for testing. Developers are inspired to try their hands on this latest non-production code, both of which to ensure that it works well with your programs and to get an overview of whether the code you are working on will get an advantage from its performance enrichments. Let's find out how CPython will make Python 3.11 more powerful and smart.

Faster CPython

According to the news, the performance advancements are accomplished only by gaining the advantage of Faster CPython – a Microsoft-funded, smartly developed project.

Faster CPython has the default interpreter known as 'CPython'. This interpreter adopts just-in-time compiler technology and finds out the code that can be advantageous from this special and smart solution. This grants instructions in executed code objects to be framed with a new instruction. The new instruction is executed faster. This, after all, makes all of Python run faster.

What is CPython?

CPython is the reference implementation of the Python programming language. Written in C and Python, CPython is the default and most widely used implementation of the Python language. CPython can be defined as both an interpreter and a compiler as it compiles Python code into bytecode before interpreting it. It has a foreign function interface with several languages, including C, in which one must explicitly write bindings in a language other than Python.

Let's look into the features in Python 3.11

Typing improvements

Python's type-hinting features make larger codebases easier to manage and analyze and have increased significantly with each revision since Python 3.5. Python 3.11 brings in several new type-hinting additions.

The Self type

Class methods that return self previously required obtuse and verbose annotations to be useful. typing. Self lets you annotate the return value of a class method as, simply, Self. You get useful and predictable results from your analysis tools for such methods.

CPython Optimizations

CPython is the reference implementation of the Python programming language. Written in C and Python, CPython is the default and most widely used implementation of the Python language. In version 3.11, the CPython interpreter is much more optimized and much faster than in version 3.10. CPython 3.11 is on average 1.22x faster than CPython 3.10 when measured with the performance benchmark suite, and compiled with GCC on Ubuntu Linux. Depending on your workload, the speedup could be up to 10–60% faster. In Python 3.11, the developers have mostly focused on faster startup and faster runtime as has been stated in the documentation.

Arbitrary string literal type

Previously, type annotations had no way to indicate a given variable needed to be a string literal—that is, a string defined in source code. The new typing.LiteralString annotation fixes that. Using the new annotation, linters can test for a variable is either a string defined in the source or a new string composed of only source-defined strings.
