What do programming terms like "while", "if", and "for" represent?

• A. Operators
• B. Keywords
• C. Variables
• D. Identifiers

Answer: (B)

The terms "while", "if", and "for" are known as keywords in programming. Keywords are reserved words in a programming language that have predefined meanings and cannot be used for any other purpose, such as naming variables or functions. They are essential for defining the structure and flow of the program. In Python, these keywords serve specific functions: "if" is used for conditional statements, "while" is used for looping based on a condition, and "for" is used for iterating over sequences like lists or ranges. Since they are integral to the syntax of the language, recognizing them as keywords is crucial for understanding how to write valid Python code properly. Other options like operators, variables, and identifiers refer to different concepts in programming. Operators perform operations on variables and values, variables are named storage locations in memory, and identifiers are names given to elements in code (like variable names and function names) that are user-defined, not reserved.
