Keyword
A keyword in computer science refers to a reserved word that has a predefined meaning within a programming language or a specific context.
Keywords cannot be used as variable names or identifiers because they are already used to represent specific commands or functionalities. They are an integral part of the syntax and structure of a programming language.
For example, in the programming language Python, there are keywords such as “if”, “else”, “for”, “while”, and “return” that have special meanings and are used to control program flow or define certain actions. These keywords are predefined and cannot be used for any other purpose.
Using a keyword as a variable name or identifier will result in a syntax error as the language cannot interpret it correctly. It’s important for programmers to be aware of the keywords in the programming language they are using, as they play a crucial role in writing correct and meaningful code.
