Python Programming Concepts

Comment: A line or fragment of code ignored by the programming language, marked by a special symbol; often used to explain code functionality.
Keyword: Special words reserved by Python with specific meanings; a comprehensive list can be found in online resources.
Constant: A fixed value that remains unchanged throughout the program's execution.
Variable: A named storage location that holds data and can be changed during execution, assigned using the assignment operator.
Assignment Operator: Represented by the symbol =, it assigns values to variables.
Increment: The process of increasing a variable's value.
Decrement: The process of decreasing a variable's value.
Data Type: Classification of data that defines the type of value a variable can hold, such as integer or string.
Object: A data entity in Python characterized by three attributes: identity, data type, and value.
String: A sequence of characters defined by the str data type, typically enclosed in quotes.
Integer: A whole number presented in Python as an object of the int data type.
Float: A representation of fractional numbers in Python, categorized as float.
Boolean: A type of object in Python (bool) that can be either True or False.
NoneType: An object type in Python with the solitary value of None, represented by NoneType.
Syntax: Defines the structural rules of programming in Python, guiding how code should be formatted and organized.
Syntax Error: A critical error in programming resulting from breaking language syntax rules, preventing code execution.
Exception: An error in code that does not halt the program's execution completely; it's often catchable and can be handled.
Operator: Symbols that perform operations on operands in expressions.
Arithmetic Operator: A specific type of operator used for performing arithmetic calculations.
Operand: A value that an operator acts upon, located on either side of the operator in an expression.
Expression: A combination of operators and operands that produces a value.
Order of Operations: A hierarchy of rules that determines the sequence in which different operations are performed in calculations.
Comparison Operator: Operators used in expressions to compare values, yielding either True or False.
Logical Operator: Operators that evaluate the truthfulness of two expressions, returning a Boolean value; these include and, or, and not.
