Final answer:
A programming language is described both by its syntax and semantics.
Step-by-step explanation:
In the context of programming languages, a programming language is described both by its syntax and semantics. Syntax refers to the structure and rules that determine how the language is written and organized, while semantics refers to the meaning and functionality of the language.
For example, in Python, the syntax includes rules for how to write statements and define variables, while the semantics determine how the statements are executed and the behavior of different Python functions.
Therefore, the statement is true. A programming language is described by both its syntax and semantics.
