An Introduction to Programming using Python

Explore Python Tutor to visualize variable creation and execution, as name and age populate the global frame and frames show each step of code in real time.

Explore Python's comparison operators for numbers, which return booleans, and see how they combine with logical operators, while noting the equality vs assignment distinction.

Write a small Python program that asks for two numbers, converts them to floats, and prints whether the numbers are not equal.

Learn a Python self-assessment solution that converts input to an integer, checks evenness with modulus two, and discusses true, false, variable naming, and logical operators.

Explore the if else construct in Python by handling true and false conditions, using proper indentation, and ensuring code blocks execute only when the condition is met.

Explore iteration-based programming in Python by using for and while loops, learning to repeat tasks via range and iterables, and recognizing infinite loops.

Shows how infinite loops run in Python, using user input and a sentinel value to exit, with break transferring execution outside the loop.

write a Python program that reads an integer, iterates digits with a while loop using modulus and division to count even digits, and prints the total.

Count the even digits in an input integer using a while loop, modulus, and integer division, while preserving the original value and introducing iteration concepts for Python data structures.

Learn to build a letter frequency histogram by iterating over a word and updating a dictionary. Observe how dictionary.get(letter, 0) initializes missing entries and increments counts, with examples like apple.

Explore dictionaries in Python, focusing on mutability and counting letter occurrences to build a histogram. Compare key checks with the get method and a zero default using the word apple.

Use a while loop to collect fruit names until the user enters q to quit. Update a dictionary of counts using get, then print the tally.

Define a function with a message parameter and print it to show how an argument replaces a parameter, and how the argument count should match the parameter count.

Initialize the maximum with the first list item, then iterate through the data with a for loop to compare each item and update the maximum when needed, returning the maximum.
