Return to PEP 572 - Python Assignment Expressions, Assignment Expressions in Programming

• Assignment expression

Here's the information formatted in MediaWiki syntax, listing programming languages that support assignment expressions:

Several programming languages support assignment within expressions, often with their unique syntax and semantics. Below is a list of some of these languages:

• C and C++: Both languages allow assignment within expressions using the assignment operator =. This feature is commonly utilized in loops and conditional statements.

• JavaScript: Supports assignment within expressions using =. It is frequently used in conditions and loops.

• PHP: Allows assignments within expressions with the = operator, usable in various contexts like conditional statements and loops.

• Ruby: Supports assignment within expressions, offering flexible syntax for various expression evaluations, including conditional assignment.

• Swift: Supports assignment within expressions but promotes careful usage to avoid confusion between assignment (=) and equality comparison (==).

• Go: Facilitates short variable declarations (:=) within expressions, particularly in if statements and loops, for concise initialization and checking.

• Rust: While Rust doesn't have direct assignment expressions like the walrus operator in Python, it supports pattern matching and “let” statements in conditions, which can serve similar purposes.

• Perl: Perl supports assignment within expressions, enabling compact and expressive code constructs.

This overview highlights the support for assignment expressions across different programming languages, reflecting the diverse approaches to incorporating this feature.

This format lists the languages and describes how each supports assignment expressions, making it suitable for inclusion in a MediaWiki-based article or documentation.
