Python Programming Fundamentals with Practical Examples

Discover Python basics, a high level, interpreted, open source language prized for readability and simple syntax. Explore its libraries and its procedural, object oriented, and functional paradigms.

Set up the Python environment by downloading and installing the latest Python from the official website, adding Python to path, and verifying with a hello world program.

Learn how to declare and use Python variables, assign values, and store data in memory. Explore naming rules, case sensitivity, and reserved words to keep code descriptive.

Learn to read user input with the input function and optional prompt string, store data in variables, and display results with print; convert strings to integers for addition.

Discover how Python comments explain code, using hash symbols for single-line comments and triple quotes for multi-line comments, to keep code understandable while not executing.

Explore Python data types, including numeric types (int, float, complex), boolean values, set and dictionary data types, and explain mutable versus immutable types and sequence data types with a list.

Demonstrate Python data types with strings, integers, floats, and a brief complex example using print and type to identify variables.

Learn how to use the input function to capture user data as strings, with an optional prompt, then convert input to integers with int and display results with print statements.

Explore arithmetic, comparison, and logical operators in Python with hands-on VS Code demos, using a=10 and b=20 to illustrate + - * / % and boolean results.

Learn how to declare and assign valid Python variables, use print to display values, and avoid invalid names; includes a VS Code walkthrough for creating variable.py and running it.

Explore Python operators, including arithmetic, comparison, logical, assignment, bitwise, membership, and identity operators, with practical code examples using user input and simple calculations.

Explore Python decision making using if and if-else statements, learning how conditions drive actions such as displaying welcome, positive numbers, or grades based on marks.

Master the elif keyword to handle multiple conditions in Python, using if, elif, and else with grading examples. See a real-world example in vscode.

Master loops in Python by iterating over sequences with for and do while loops, use range to generate 1–100, including odd and even numbers, across lists, tuples, dictionaries, and strings.

Master the Python while loop: execute code while a condition is true, with examples using lists, tuples, and len-based length checks.

Explore how continue and break statements control Python loops, with for and while examples that skip specific values and terminate iterations.

Learn to build a beginner-level Python program that checks whether a user-entered number is positive, negative, or zero. Use input, int conversion, and an if-elif-else structure to print the result.

Explore how to print the first ten even numbers with a Python for loop, using the range function in VS Code, and save the script as for loop.py.

Define and reuse code by creating functions with the def keyword, specify parameters, and return results; call functions to perform tasks like adding users or numbers, reducing duplication.

Explore how Python lists serve as arrays by indexing, slicing, appending, removing, and sorting diverse data types, and contrast with traditional arrays; next class covers the array module.

Learn to use Python's built-in array module to create and manipulate integer arrays, import array, create arrays, access indices, and iterate with a for loop.

Learn how to install, upgrade, and uninstall Python packages using pip, including pandas, Django, and TensorFlow, with practical command examples.

Learn how strings in Python are sequences of characters, defined with single or double quotes, accessed by index, sliced, concatenated, and formatted using format with curly braces.

Explore Python’s built-in number types—integers, floats, and complex numbers—through examples of arithmetic operations and type checks to support math and physics applications.

Learn to write a Python function that computes a triangle area using base and width. See a VS Code demo of input, base and width, and area divided by two.

Identify the maximum number in a Python list using the max function in VS Code. See how a max_num.py script prints the maximum value from a sample list.

Learn to count the number of vowels in a user-entered string by iterating each character, checking against vowels a, e, i, o, u in both cases, and displaying the total.
