Learn how to declare and use Python variables as containers for data values, assign with the equals sign, print without quotes, and apply naming rules, case sensitivity, and overwriting values.

Explore Python data types, including string, integer, float, complex, list, tuple, range, dictionary, set, boolean, and none type, and learn to print values and inspect their types.

Explore typecasting in Python by converting data types with int, float, and string constructors, and inspect types with the type function.

Learn how to prompt for user input in Python, store it in variables, and build interactive programs. Convert inputs to integers for arithmetic and display the sum of two numbers.

Explore Python strings by using single or double quotes, escaping quotes with backslashes, and printing strings. Learn string indexing, access characters with brackets, and compute length with len.

Learn string slicing in Python by setting start and end indices to return character ranges, including zero-based indexing, end exclusion, and negative indices.

Learn to modify strings in Python using upper, lower, strip, replace, and split, with practical examples transforming text and removing whitespace.

Learn how to concatenate strings in Python using the plus operator and print the result with a space. Use a comma to join strings and numbers.

Learn to format strings in python with f-strings, using placeholders and curly braces to concatenate strings and numbers. See how modifiers and expressions refine output, including two decimal places.

Learn to build a Python program that calculates a rectangle’s area by prompting for length and width, casting inputs to float, computing area, and displaying the result with a unit.

Learn to build a primitive shopping cart in Python by prompting for item, price, and quantity; compute the total and print the cart using f-strings.

Learn how to use arithmetic operators in Python to perform addition, subtraction, multiplication, division, modulus, exponent, and floor division, with practical examples.

Learn how assignment operators in Python modify variables in place. See examples like x = 5, x += 3, x -= 3, x *= 3, x /= 3, x %= 3, x **= 3, and x //= 3 with printouts showing results.

Explore how Python's comparison operators compare two values and return a boolean true or false, using x and y 20 and 10 to illustrate equal and not equal.

Learn python logical operators and, or, and not to combine conditional statements. See how and requires both conditions true, or requires one true, and not inverts the result.

Explore Python identity operators, including is and is not, and learn how they test if two variables reference the same memory address rather than equal values.

Explore Python membership operators, using in and not in to test whether a sequence exists in an object, with practical examples on sets and strings.

Explore conditional statements in Python using if, elif, and else, comparing values with operators, and mastering indentation, logical operators, and ternary expressions.

Build a Python weight converter that prompts for a weight and unit, converts between kilograms and pounds, rounds to one decimal, and handles uppercase or lowercase unit input.

Learn to build a Python temperature conversion program that prompts for Celsius or Fahrenheit, converts between units, rounds results to one decimal, and handles invalid input with clear prompts.

Create lists in Python using square brackets, store multiple items, and print them. Explore list length with len, duplicates, and mixed data types, including strings, integers, booleans, and more.

Learn how to access list items in Python using zero-based indexing, negative indexing, and slicing to retrieve ranges such as Apple and Banana.

Learn to update Python lists by index and by slice, starting at zero, then add elements and replace ranges with end-exclusive slicing.

Learn how to add items to a Python list using append, insert, and extend, with examples of appending orange, inserting mango at index zero, and extending with another list.

Learn to remove items from a Python list using remove, pop, del, and clear; understand index-based removal, first vs last occurrences, and how delete eliminates the entire list.

Explore sorting lists alphanumerically in Python using the sort method, switch to descending order with the reverse parameter set to true, and compare with the reverse method.

Copy list elements in Python using the copy method, the list constructor, and the slice operator. The lesson demonstrates copying from one list to another.

Learn how to join two lists in Python using the plus operator and the extend method, creating a concatenated list and printing the combined result.
