Study Notes

Executing Python Scripts

Create Python files with a .py extension to execute multiple statements.

Example script:

print("This is Python Script.")
print("Welcome to Python Tutorial by TutorialsTeacher.com")

Use command prompt to navigate to the file and execute using python myPythonScript.py.

Python IDLE

IDLE (Integrated Development and Learning Environment) is included with Python installations on Windows and Mac, available for download on Linux.
Suitable for beginners due to its simplicity and minimal features.
Functions as an interactive interpreter and file editor, displaying a blank Python interpreter window upon opening.

Different IDEs for Python Development

IDLE
- Default editor for Python, suitable for beginners.
- Compatible with Mac OS, Windows, and Linux.
- Free to use with features like syntax highlighting, error messages, smart indenting, and debugging capabilities.
PyCharm
- Popular IDE by JetBrains for professional developers, focusing on large projects.
- Offers freemium pricing.
- Notable for JavaScript and TypeScript support, smart code navigation, and database access.
Visual Studio Code
- Open-source IDE from Microsoft, favored for Python development.
- Lightweight with powerful features, also free.
- Known for smart code completion, Git integration, and customizable extensions.
Sublime Text 3
- Highly customizable code editor supporting multiple languages.
- Fast and reliable with free pricing.
- Features syntax highlighting, custom user commands, and project management.

Python Operators

Arithmetic Operators: Perform mathematical operations (e.g., +, -, *, /, %).
Comparison Operators: Assess relational conditions (e.g., ==, !=).

Python Built-in Function: dir()

Returns a list of attributes and methods of an object.
Without parameters, it lists names in the current scope.
Differentiates behavior among various object types (e.g., classes, modules).

Python Packages

Organize files into folders for easy management and modular development.
A package contains multiple related modules, physically represented as a folder with an __init__.py file.

NumPy Module

Library for numerical operations on multidimensional arrays.
Enables mathematical, logical operations, Fourier transforms, and shape manipulation.

SciPy Module

Open-source library for scientific computations, built on NumPy.
Provides routines for numerical integration and optimization.

Pandas Module

An open-source library designed for high-performance data manipulation.
Key features include a fast DataFrame object, data restructuring, and efficient data alignment.
Preferred for data analysis due to its simplicity and expressiveness.
