That is, in order to simplify coding, without losing type information, with the help of ‘float | int’ substitute. For instance, when a programmer misses using ‘:’ before blocks, the interpreter will display the following message: Synta圎rror: expected ‘:’Īdditionally, the latest version simplifies the static type system. However, in version 3.10, the interpreter will now provide more precise and specific information while parsing the code. The development team at Python has improved its debugging capabilities and clarity of error messages.Įarlier, while programming in Python, developers would get vague messages like: ‘Synta圎rror: unexpected EOF while parsing’ If the exact match is not confirmed, a wildcard when provided, can be used as the matching case.Executing action associated with a pattern of the confirmed match.Comparing the subject with each pattern in case statement from top to bottom until a match is confirmed.Evaluating the subject in the match statement.Using data with type and shape (the subject).The generic syntax of pattern matching is as follows: The syntax around the two statements - ‘match’ and ‘case’ expanded, can now be used to extract information from complex data types, branch the structure of data or apply other specific actions to varied data forms. Patterns for comparison can consist of sequences - lists and types mapping structures - dictionaries primitive data types or class instances. Structural pattern matching has been added in the form of two statements - ‘match statement’ and ‘case statements’ of patterns with associated actions.

That is, it makes it possible to write code quickly encompassing a variety of scenarios.

This update expands the range of possibilities and is going to benefit those who deal intensively with data structures. Structural pattern matching (PEP 634) in Python allows one to match variables against patterns of values - an object with a certain property set to a certain value.

Today, we list the major features of Python 3.10.

While there are several new features in the latest in-development version, the most significant upgrade has to be the language syntax, since async. Python released its latest upgrade, Python 3.10, on October 04, 2021, soon after the 30th anniversary of the programming language. According to the TIOBE Index for October 2021, Python is the most popular programming language in the global developers’ community. High-level, general-purpose programming language Python emphasises code readability with the use of indentation.
