Top 10 Recent Python Launches Programmers Should Know – Crypto News Flash

Python launched Python 3.11. Here are the top 10 recent Python launches programmers should know

Python launches Python 3.11 and developers are encouraged to try out this latest version on non-production code, both to verify that it works with your programs and to get an idea of whether your code will benefit from its performance enhancements. Python 3.10 already had better error reporting, thanks to the new parser used in the interpreter. Python 3.11 expands on that by providing detailed feedback about what specific part of a given expression caused an error. This article features the top 10 recent Python launches programmers should know.

Python 3.11 (24 October 2022)

Python 3.11 is between 10-60% faster than Python 3.10. On average, it measures a 1.25x speedup on the standard benchmark suite. It introduces language features that enable a program to raise and handle multiple unrelated exceptions simultaneously. The builtin types ExceptionGroup and BaseExceptionGroup make it possible to group exceptions and raise them together, and the new except* syntax generalizes except to match subgroups of exception groups.

Python 3.10.7 (6 September 2022)

This version supports the use of enclosing parentheses for continuation across multiple lines in context managers. This allows formatting an extended collection of context managers in multiple lines in a similar way as it was previously possible with import statements.

Python 3.10.6  (8 August 2022)

Structural pattern matching has been added in the form of a match statement and case statements of patterns with associated actions. Patterns consist of sequences, mappings, primitive data types as well as class instances. Pattern matching enables programs to extract information from complex data types, branch on the structure of data, and apply specific actions based on different forms of data.

Python 3.10.5 (6 June 2022)

This version brings more precise and reliable line numbers for debugging, profiling, and coverage tools. Tracing events, with the correct line number, are generated for all lines of code executed and only for those that are executed.

Python 3.10.4 (24 March 2022)

Readers may be aware of pattern matching through the simple example of matching a subject (data object) to a literal (pattern) with the switch statement found in C, Java, or JavaScript (and many other languages). Often the switch statement is used for the comparison of an object/expression with case statements containing literals.

Python 3.10.3 (16 March 2022)

You can use positional parameters with some built-in classes that provide an ordering for their attributes (e.g., data classes). You can also define a specific position for attributes in patterns by setting the __match_args__ special attribute in your classes.

Python 3.10.2 (14 January 2022)

When printing NameError raised by the interpreter, PyErr_Display() will offer suggestions of similar variable names in the function that the exception was raised from so and so.

Python 3.10.1 (6 December 2021)

When parsing code that contains unclosed parentheses or brackets the interpreter now includes the location of the unclosed bracket of parentheses instead of displaying SyntaxError: unexpected EOF while parsing or pointing to some incorrect location.

Python 3.10.0 (4 October 2021)

Readers may be aware of pattern matching through the simple example of matching a subject (data object) to a literal (pattern) with the switch statement found in C, Java or JavaScript (and many other languages). Often the switch statement is used for the comparison of an object/expression with case statements containing literals.

Python 3.9.14 (6 September 2021)

You can use positional parameters with some built-in classes that provide an ordering for their attributes (e.g. data classes). You can also define a specific position for attributes in patterns by setting the __match_args__  special attribute in your classes.
