Python Keywords

Subscribe Contact


Python keywords are reserved words that have a specific, predefined meaning in the Python programming language. These words cannot be used as identifiers, such as names for variables, functions, or classes, because they are already used by the language syntax for defining the structure and control flow of the code. Examples of Python keywords include if, else, for, while, break, continue, def, return, class, try, except, import, from, as, with, True, False, and None. Each of these keywords serves a unique purpose in Python, ranging from creating conditional statements, loops, functions, classes, to handling exceptions and importing modules. The number and nature of keywords can vary slightly between different versions of Python, but they are all integral to the language's structure. Understanding and correctly using these keywords is essential for writing syntactically correct and efficient Python code.
