    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.

    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
