SolidPoint Python Full Course for Beginners [2025] Programming with Mosh UCWv7vMbMWH4-V0ZXdmDpPBA Topics Summary Copy Link Python Implementations Overview Python Mastery: Foundations - A Comprehensive Summary This course is designed to take you from zero to proficient in Python, equipping you for fields like AI, machine learning, web development, and automation even with no prior coding experience. Instructor M. Hamadani 20+ years experience, millions taught emphasizes a step-by-step, practical approach. Why Python Python is booming in popularity across diverse fields not just software development, but also data science, mathematics, and more. It stands out for its readability and conciseness. For example, extracting the first three characters of hello world is dramatically simpler in Python than in C or JavaScript. python text = hello world firstthree = text:3 # Pythons elegant solution printfirstthree # Output: hel Python is a multi-purpose language, applicable to data analysis, AI, scripting, web development, and even security testing. Python developers currently earn an average of over 115,000 in the US according to I data from March 2018. Key Python Advantages: High-Level: Handles complex tasks like memory management automatically, freeing you to focus on logic. Cross-Platform: Runs on Windows, Mac, and Linux. Large Community: Abundant support and resources available. Extensive Ecosystem: A wealth of libraries and frameworks exist for almost any task. Python Versions: The course focuses on Python 3, the future of the language Python 2 support ended in 2020. Setting Up Your Environment: Download the latest Python 3 version from tps:// Crucially, on Windows, check Add Python to PATH during installation. This avoids headaches later. Verify installation: Windows: Open terminal search for terminal and type python --version Mac: Press Command + Space, type terminal, and type python3 --version The Python Interpreter: The Python interpreter executes your code. You can interact with it directly in the terminal a great way to experiment: python 2 + 2 4 2 1 True 2 5 False Code Editors IDEs: While you can code directly in the interpreter, its best to use a code editor or Integrated Development Environment IDE. Code Editors e.g., VS Code, Atom, Sublime: Lightweight, customizable. IDEs e.g., PyCharm: Feature-rich, with auto-completion, debugging, and testing tools. The course uses VS Code, with the option to install plugins to transform it into a powerful IDE. Install VS Code from tps:// Essential VS Code Setup: Create a new folder e.g., hello world. Open the folder in VS Code. Create a new Python file e.g., ensure the file extension is .py. Install the Python extension in VS Code. Enable format on save for automatic code formatting ensures consistency with PEP 8 style guide. Running Python Code: Terminal: python Windows or python3 Mac/Linux VS Code: Use the play button or set a keyboard shortcut e.g., Ctrl+R. Core Programming Concepts Introduced: Variables: Named storage locations for data. Descriptive names, lowercase with underscores e.g., studentcount are key. Data Types: Integers: Whole numbers e.g., 10 Floats: Numbers with decimal points e.g., 4.99 Booleans: True or False values. Case-sensitive Strings: Text enclosed in single or double quotes e.g., Python Programming. Triple quotes for multi-line strings. String Operations: lenstring: Returns the length of a string. stringindex: Accesses a character at a specific index 0-based. stringstart:end: Slices the string. , : Converts case. : Removes leading/trailing whitespace. ubstring: Finds the index of a substring. ceold, new: Replaces text. in operator: Checks if a substring exists. Formatted String Literals f-strings: A concise way to embed expressions within strings: python name = Alice age = 30 printfMy name is name and I am age years old. Mathematical Operators: +, -, *, /, // integer division, modulus, ** exponent. Augmented assignment e.g., x += 1 for conciseness. Input: inputPrompt: gets data from the user as a string. Remember to convert to the desired type e.g., intinput... . Conditional Statements: if, elif, else for making decisions based on conditions. Logical Operators: and, or, not for combining conditions. Short-circuiting behavior. Loops: for loops: Iterate over a sequence e.g., range, string, list. while loops: Repeat as long as a condition is true. break statement to exit a loop prematurely. This introductory section lays the foundation for more advanced Python concepts. The course stresses clean coding practices PEP 8 style guide and encourages experimentation.
