Keywords in Python

Keywords in Python:


Keywords are important elements in programming languages, which are given special meanings and functions. These are special words used during programming to define specific tasks. Keywords are used in various programming languages, such as C, C++, Java, Python, etc.

Characteristics of Keywords:
  • Reserved: Keywords are used for special tasks and cannot be used as other identifiers in a program.
  • Defined Functionality: Each keyword has a definite function, such as making decisions, running loops, defining a function or class, etc.
  • Case Sensitivity: Many programming languages are case-sensitive for keywords, meaning `If` and `if` are considered two different keywords.

Types of Keywords:
Keywords can generally be classified into the following categories:
  • Control Flow Keywords: Used to control the flow of the program (e.g., `if`, `else`, `for`, `while`).
  • Data Type Keywords: Used to define data types (e.g., `int`, `float`, `char`).
  • Structure Keywords: Used for creating structures and functions (e.g., `class`, `struct`, `def`).
  • Utility Keywords: Used for special tasks (e.g., `return`, `break`, `continue`).

Advantages of Keywords:
Clarity, maintenance, and consistency. They make the program more explicit and understandable.
