Learn to implement a conditional statement that checks if a number is between 10 and 20 inclusive or equal to 25, using and and or operators.

write a program that compares two numbers using comparison operators, printing whether x is less than, equal to, or greater than y, and explain the if-else flow.

Learn to truncate a floating point number to its integer part in Python using the math library and math.trunc, converting input to float, and printing the result.

Use Python and the math.ceil function from the math library to calculate the total pages needed for a given total lines and lines per page, rounding up.

Write a Python program to compute years to double an investment using the logarithm formula time = log(2)/log(1+rate). Read rate as a decimal and print the result.

Learn to use Python for loops to iterate numbers with the range function. The start is inclusive and the end exclusive, printing 1 through 5 with i.

Learn how nested loops work by using an outer loop and an inner loop to iterate over ranges, print i and j, and apply to multi‑dimensional data such as matrices.

Learn how the continue statement skips the current loop iteration and moves on to the next. A Python example shows it printing 1, 3, and 5 by skipping even numbers.

Count down from five to one using a while loop in Python, printing each value and decrementing by one until zero, then display blast-off.

Define and call functions in Python using def, name, parentheses, and arguments, distinguishing built-in and user-defined functions. Learn how functions reduce repetition and improve code readability.

Learn how global variables are declared outside functions and accessible from any function, illustrated by declaring a hello world message and printing it from inside and outside a function.

Explore how local variables shadow global ones in Python, and learn to use the global keyword to modify a global number from inside a function.

Define a function check_even_odd to determine if a given number is even or odd using modulo two, printing 'even' or 'odd', with examples like 10 and 7 to show efficiency.

Learn to use functions with default values in Python by defining default parameters, so calls with or without arguments print greetings like hello name or hello friend.

Use return statements to retrieve values from functions, and store them in variables. See how an add function returns a plus b and enables code reuse.

Create a Python function using def to convert Celsius to Fahrenheit with the formula Celsius * 9/5 + 32, returning and printing the result for sample temps.

Learn how to find the third largest number by converting a list to a set to remove duplicates, sorting the unique numbers, and indexing with minus three.

Learn to append two lists in Python using the plus operator; combine list one and list two, then the append list function returns list one plus list two.

Create a numbers list with 10, 20, 30; compute its sum with the sum function, assign it to total, and print the total (showing 60 for this example).

Learn to reverse a Python list by using the original list and a reversed version created with colon colon minus 1, then print both the original and reversed lists.

Learn to compute element-wise sum of two tuples in Python by using zip to iterate concurrently, summing elements with a for loop, and returning a tuple.

Create a tuple of favorite colors and print the first and last elements using zero-based and negative indexing. Demonstrate indexing from left and right to access colors.

Create and print sets in Python using the set function, including an empty set, a numbers set, and a mixed data set with int, float, and string elements.

Learn how to compute set difference in Python by subtracting sets or using the difference method to find elements in set 1 not in set 2 and print them.

Learn how to obtain unique values from a list by converting it to a set, which removes duplicates, and optionally convert the set back to a list for the output.

Compute the symmetric difference of two sets, yielding elements in either set but not in both, as shown with {1,2,3} and {3,4,5}, using Python's symmetric_difference.

Learn to find the second smallest number in a list by removing duplicates with a set, sorting the unique numbers, and selecting the second element.

Explore membership testing in Python sets using in and not in, verify if elements exist, and understand true/false outcomes with practical examples.

Explore Python set comprehension by building a set in one line with an expression and optional conditions. Create a set of squares from 1 to 5 using range and x**2.

Explore set comprehension in Python by building a set of even numbers from 1 to 10 using range and modulo; print the resulting evens 2, 4, 6, 8, 10.

Learn to extract unique words from a sentence by converting a split string into a set, which removes duplicates and prints the resulting unique words in Python.

Learn to add and update key-value pairs in Python dictionaries, using square brackets to add new keys and modify existing ones, then print the updated dictionary.

Remove items from a dictionary with the del keyword, as shown by deleting the city key from the person dictionary and printing the updated result.

Create and print a dictionary containing a person's name, age, and city, then iterate with a for loop using items() to print each key and value.

Remove a key-value pair from a Python dictionary using the del keyword, demonstrated on a car dictionary with brand, model, and year. See the updated dictionary without the removed key.

Learn formatted printing in Python using f-strings to create clean, readable output. See how to embed variables inside curly braces for concise string construction with the print function.

Learn to use named arguments in string formatting by passing name and messages, demonstrating arguments via curly braces and the format function, and printing personalized output.

Master Python text formatting by learning padding and alignment with format specifiers, enabling right, left, and center alignment within a specified width using print and curly brace syntax.
