Study Notes
-
Python is an interpreted, high-level, general-purpose programming language.
-
Its design philosophy emphasizes code readability through significant indentation.
-
Python's extensive libraries support various programming paradigms, including object-oriented, imperative, and functional approaches.
Key Features
-
Interpreted: Python code is executed line by line by an interpreter, unlike compiled languages that translate the entire code into machine code beforehand. This enables faster development, but slower execution for computationally intensive tasks.
-
High-level: Python abstracts low-level details like memory management, simplifying coding but potentially limiting direct system resource control.
-
General-purpose: Python is applicable across diverse domains, from web development and scientific computing to data analysis.
Data Types
-
Numeric: Includes integers, floats, and complex numbers, supporting mathematical operations.
-
Boolean: Represents truth values (True/False), used in conditional statements and logical operations.
-
String: Represents sequences of characters, offering string manipulation methods.
-
List: Ordered, mutable sequence of items, accommodating various data types.
-
Tuple: Ordered, immutable sequence of items for fixed data collections.
-
Dictionary: Collection of key-value pairs for data storage and retrieval based on keys.
Control Flow
-
Conditional Statements:
if,elif, andelsefor decision-making based on conditions. -
Looping:
forandwhileloops for repeated execution.
Functions
-
Python encloses code blocks into functions, promoting modularity and reusability.
-
Functions can accept arguments and return values.
-
Python supports function overloading (defining multiple functions with the same name but different parameters).
Modules and Packages
-
Modules: Python files containing reusable functions and data, aiding in code organization.
-
Packages: Collections of modules that structure larger projects, essential for complex application development.
Object-Oriented Programming (OOP)
-
Python supports OOP through classes to define objects and inherit functionalities from existing classes.
-
Class structures are vital for building flexible and complex applications.
Libraries
-
Python's extensive libraries enable diverse tasks:
-
NumPy: For numerical calculations and array manipulation; key for scientific computing.
-
Pandas: For data analysis and manipulation; excellent for data processing.
-
Matplotlib: For data visualization.
-
Scikit-learn: A machine learning library with various algorithms and tools for data prediction.
-
Requests: Simplifies HTTP requests for interacting with web resources.
-
Django and Flask: Popular web development frameworks for building dynamic web applications.
-
Syntax Highlights
-
Indentation: Indentation is critical for code blocks within loops, conditional statements, and functions.
-
Comments: Use the
#symbol for comments to clarify code. -
Variable Declaration: Python is dynamically typed; variables need no explicit type declarations.
-
Data structures: Includes lists, tuples, dictionaries, and sets for data organization.
Error Handling
-
try...exceptblocks: Handle potential exceptions during program execution; crucial for error management and program stability.
File Handling
- Python provides features to read and write text files for data input/output operations.
Common Operators
-
Arithmetic: Standard arithmetic operators (+, -, *, /, //, %, **)
-
Comparison: Comparison operators (==, !=, >, <, >=, <=)
-
Logical: Logical operators (and, or, not)
Other Concepts
-
Built-in Functions: Python offers many built-in functions like
len(),print(), as part of the core language. -
Input/Output: Python supports user interaction (input) and output to the console.
General Applicability
- Python's versatility applies to web development, scripting, data science, machine learning, automation, and game development.
Development Environment
-
Python runs on various operating systems (Windows, macOS, Linux).
-
Integrated Development Environments (IDEs) and code editors help with developing, testing, and debugging Python code.
