100 Days of Code™: The Complete Python Pro Bootcamp

Master data types, numbers, operations, type conversion, and f-strings while building a tip calculator that splits a bill among friends.

Explore core python data types, including strings, integers, floats, and booleans, with practical examples of zero-based indexing, subscripting, concatenation, and numeric operations.

Discover how type errors occur when functions receive the wrong data type, and learn type checking and type conversion across Python's primitive types like string, int, float, and bool.

Explore Python's arithmetic operators, including addition, subtraction, multiplication, division, integer division, and exponentiation; learn implicit type casting, and pemdaslr precedence with left-to-right evaluation.

Build a tip calculator that takes the bill, tip percentage, and number of people. Compute each person's share and round to two decimals using f-strings and type conversion.

Master conditional statements, if/else/elif, logical operators, code blocks, and scope with global and local namespacing as you build a choose-your-own-adventure game in Python.

Explore control flow with if/else in Python, using indentation and comparison operators to decide actions, such as a bathtub overflow or roller coaster height checks.

Learn how the modulo operator returns the remainder of a division and, by converting input to int, use an if statement to tell whether the number is even or odd.

Learn to chain multiple if statements in a roller coaster ticketing flow to add a photo for $3, updating the bill with += and handling input and indentation in Python.

Build a Python pizza delivery program that calculates the bill from size using if statements. Pepperoni adds 2 for small or 3 for others; extra cheese adds 1; print total.

Learn to combine conditions in Python using and, or, and not within if statements, and apply it to age-based logic like 45 to 55.

Build a treasure island choose-your-own-adventure game in Python using conditionals (if, elif, else) with user input, flowchart guidance, and ASCII art, resulting in game over or win outcomes.

Master randomization in Python using the random module and lists, and build a rock paper scissors game by the end of the day.

Learn to generate randomness in Python with the random module, including the mersenne twister, using randint and random for floats, and uniform ranges, plus a heads or tails example.

Explore how Python lists serve as a data structure to store ordered data with square brackets and indexing. Use append and extend to modify the list.

Learn to select a random name from a list in Python by using random.choice or random.randint, with import random and list indexing, to print a different name each run.

Learn to avoid index errors by understanding list bounds and off-by-one mistakes, with a nested list example using the dirty_dozen fruits and vegetables.

Build a rock, paper, scissors game in Python that uses random choice, user input, and if statements to determine win, lose, or draw, with input validation and ASCII art.

Commit to practice in the coding editor; programming requires hours of effort, not passive watching, and treat coding like a gym—push reps, rest, and return as a Python programmer.

Build a password generator to create strong, unique passwords using letters, symbols, and numbers, while learning about password reuse and checking for breaches on haveibeenpwned.com.

Learn how to use the for loop with Python lists to iterate over items, access each element, print results, and understand indentation, the in keyword, and block execution.

learn how Python uses built-in sum to total scores and how to replicate max with a for loop on a list, using a max_score variable and conditional updates.

Learn to use for loops with the range() function to generate numbers without lists. Iterate from 1 to 100 with an adjustable step and accumulate totals to reveal 5050.

Tackle the day 5 project to build a Python password generator that asks for letters, symbols, and numbers, offering easy sequential and hard randomized ordering.

Persist through tough challenges and practice everyday to turn overwhelm into understanding as you prove that hard work and perseverance beat raw talent, finishing with confidence in your Python skills.

Master code blocks, indentation, and functions, explore while loops, and practice with a Karel-like robot to write code that navigates a randomly generated maze by day’s end.

Define and call Python functions using def, explore built-in functions like print and len, and refactor code with custom functions such as turn_right to improve readability and reuse.

Learn to encapsulate move and turns with functions, define turn_right and jump, and use a for loop with range to solve six hurdles with minimal, readable code.

Learn Python indentation by visualizing blocks inside functions, if statements, and loops, using four spaces to define scope; understand spaces vs tabs and Python 3 rules.

Explore how the while loop runs while a condition is true, contrast it with for loops, and see not at_goal logic guiding a hurdle challenge.

Master the while loop by handling random wall hurdles in Reeborg's World, using if statements, not front, not at goal, and a refined jump function to reach the goal.

Learn to adapt a hurdle jumping function for variable-height walls using while loops and sensor checks, guiding a robot to the final flag with wall on right and front clear.

Apply a right-wall-following algorithm in Reeborg's world to guide a robot from any starting position to the maze goal using while loops, if/elif/else, and tests like front_is_clear and right_is_clear.

Embrace the struggle of learning a new skill, like windsurfing on day six, because the pain signals progress and you keep going by practicing your hat tricks.

Day 7 guides you to build a hangman style word guessing game using a random word and lives, while reviewing for and while loops, if/else, lists, strings, range, and modules.

Map the Hangman game's logic with a flowchart, from generating a random word and blanks to processing guesses and determining game over.

Step 1 guides you through three TODOs to randomly pick a word from word_list into chosen_word, prompt for a letter, lowercase it, and print Right or Wrong.

Step 2 teaches replacing blanks with guesses in hangman by building a display string that shows guessed letters and underscores, using a for loop and word length.

Step 3 introduces a while loop to allow repeated guesses in the hangman game, and preserves previous correct letters with a correct_letters list until all letters are revealed.

Set a lives variable to six, decrement it on incorrect guesses, then display the corresponding ASCII art stage and print You lose at zero.

Commit to daily practice and show up each day, even through breaks or busy schedules, because consistent repetition keeps content fresh and progress linear when you follow the course order.

Explore functions with inputs and the difference between arguments and parameters, then build a Caesar cipher encoder and decoder to encrypt and decrypt messages using a shift value.

Learn how to create a Python function with multiple inputs using positional and keyword arguments. The lesson uses greet_with(name, location) to show how argument order and binding affect output.

Create a Python encryption tool that encodes and decodes text with a Caesar cipher shift, uses an index function and modulo to wrap around the alphabet.

Learn to implement Caesar cipher decryption by building a decrypt function, shifting letters backward, and then merge encrypt and decrypt into a Caesar cipher function that handles encode or decode.

Finish the caesar cipher project by importing and printing art.py logo, preserving non alphabet characters during encoding, and implementing a restart loop to encode or decode again.

Identify what motivates you to learn Python, reflect on why you're doing this for your career and family, and post your goals where you'll see them to stay on track.
