Study Notes
Python Programming Overview
- Python is a general-purpose, dynamic, high-level, and interpreted programming language
- Supports object-oriented, imperative, and functional programming paradigms
- Used for web development, machine learning, and more
- Python's syntax is concise and readable, with automatic memory management.
Parts of Python Programming
- Keywords: Predefined reserved words used in Python syntax
- Identifiers: User-defined names for variables, functions, classes, etc.
- Statements and Expressions: Instructions that Python interprets and executes
- Variables: Containers that store values
- Operators: Symbols used to perform operations on values (e.g., arithmetic, comparison)
Data Types
- Numeric:
int
(integers),float
(floating-point numbers),complex
(complex numbers) - Text:
str
(strings of characters) - Boolean:
bool
(Boolean values:True
orFalse
) - Sequence:
list
(ordered, mutable sequence),tuple
(ordered, immutable sequence),range
- Mapping:
dict
(key-value pairs) - Set:
set
(unordered collection of unique elements),frozenset
(immutable set) - Binary:
bytes
,bytearray
,memoryview
- NoneType: Represents the absence of a value
Control Flow Statements
- Conditional Statements (if, elif, else): Execute different blocks of code based on conditions
- Loops (for and while): Repeat a block of code multiple times
- Break and Continue: Used to control loop execution flow
- Pass Statement: Acts as a placeholder when no action is needed
Functions
- Function Definition: Creating a reusable block of code
- Parameters: Input values passed to the function
- Return Values: Data returned from the function
- Void Functions: Do not return a value
- Keyword Arguments: Arguments passed with their parameter names
- args/kwargs: Variable number of positional/keyword arguments
Exceptions
- Exception Handling (try, except, finally): Handles errors gracefully within a program
Modules
- Common Modules:
math
,random
,datetime
,os
,json
,re
,csv
- Imports: Using modules in Python programs
Python Programming Additional Concepts
- Operator Precedence: Determines the order of operations in expressions
- Operator Associativity: Determines the order of operations involving operators with the same precedence
- Input and Output: Reading user input, displaying output
- Dynamic and Strong Typing: How Python handles data types at runtime.
- Scope/Lifetime of Variables: Defining variable accessibility and duration
