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 eitherTrue
orFalse
. -
NoneType: An object type in Python with the solitary value of
None
, represented byNoneType
. - 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
orFalse
. -
Logical Operator: Operators that evaluate the truthfulness of two expressions, returning a Boolean value; these include
and
,or
, andnot
.
