🏗 Final Project

Mini Python Toolbox

Build a utility module: a collection of 8+ functions you've mastered, including list processing, dictionary processing, and recursion. Your crowning achievement!

⚡

8+ Functions

Each with a docstring

🔄

1+ Recursive

At least one recursive function

📋

1+ List Processor

Takes or returns a list

📖

1+ Dict Processor

Takes or returns a dict

🔨

2 Original

Two functions of your own design

✅

All Tested

Auto-graded via test suite

Your Toolbox

# ============================================
#   🧰 MINI PYTHON TOOLBOX
#   Your collection of reusable functions!
# ============================================

# --- Math Functions ---

def factorial(n):
    """Return n! (n factorial). Uses recursion."""
    # TODO: Implement (base case: n <= 1 returns 1)
    pass

def power(base, exp):
    """Return base raised to exp using recursion."""
    # TODO: Implement (base case: exp == 0 returns 1)
    pass

def clamp(value, low, high):
    """Return value clamped between low and high."""
    # TODO: Return low if value < low, high if value > high, else value
    pass

# --- List Functions ---

def mean(numbers):
    """Return the average of a list of numbers."""
    # TODO: sum / len
    pass

def median(numbers):
    """Return the median of a list of numbers."""
    # TODO: Sort, pick middle (or avg of two middles)
    pass

def unique(items):
    """Return a new list with duplicates removed (preserving order)."""
    # TODO: Loop, check 'not in', append
    pass

# --- Dictionary Functions ---

def word_count(text):
    """Return a dict mapping each word to its count."""
    # TODO: Split text, count each word
    pass

def invert_dict(d):
    """Return a new dict with keys and values swapped."""
    # TODO: Loop through .items(), swap key/value
    pass

# --- String Functions ---

def is_palindrome(s):
    """Return True if s reads the same forward and backward. Recursive."""
    # TODO: Compare first and last chars, recurse on middle
    pass

def title_case(text):
    """Return text with the first letter of each word capitalized."""
    # TODO: Split, capitalize each, join
    pass
