Python Keywords Explained: Beginner-Friendly Guide
Python keywords are reserved words that form the foundation of Python syntax. These words have predefined meanings and cannot be used as variable or function names. Understanding Python keywords is essential for writing correct and efficient Python programs.
What Are Python Keywords?
Python keywords control the structure and flow of a program. They help Python understand decisions, loops, functions, and error handling.
Common Python keywords include:
-
if,elif,else -
for,while -
def,return -
try,except,finally -
class,import
Python Hello World Example
The Hello World program is usually the first step in learning Python.
The print() function displays output on the screen and helps beginners understand basic Python syntax.
