# =============================================================================
# Exercise 1: Introduce yourself
#
# Print three lines:
#   - Your name
#   - Your favorite programming language
#   - Why you're learning Python
#
# Example output:
#   Hi, I'm Alice!
#   My favorite language is JavaScript.
#   I'm learning Python because it's everywhere!
# =============================================================================

def exercise_1():
    # YOUR CODE HERE
    pass


# =============================================================================
# Exercise 2: Build a date
#
# Using a SINGLE print() call with the sep parameter, print today's date
# in the format: 2025-02-09
#
# Hint: print("2025", "02", "09", sep=???)
# =============================================================================

def exercise_2():
    # YOUR CODE HERE
    pass


# =============================================================================
# Exercise 3: ASCII art
#
# Print this simple house using print() statements:
#
#     /\
#    /  \
#   /    \
#  |------|
#  |      |
#  |  []  |
#  |______|
#
# Hint: You might find it easier to use a multi-line string with triple quotes
# =============================================================================

def exercise_3():
    # YOUR CODE HERE
    pass


# =============================================================================
# Exercise 4: Loading bar
#
# Using print() with the end parameter, create output that looks like:
#   Loading: [#####] Complete!
#
# The catch: do it with THREE separate print() calls:
#   1. Print "Loading: ["
#   2. Print "#####"
#   3. Print "] Complete!"
#
# Hint: Use end="" to prevent print from adding a newline
# =============================================================================

def exercise_4():
    # YOUR CODE HERE
    pass


# =============================================================================
# Exercise 5: Receipt
#
# Print a simple receipt using \t (tab) for alignment:
#
#   ===== RECEIPT =====
#   Item        Price
#   Coffee      $4.50
#   Muffin      $3.25
#   Juice       $5.00
#   ===================
#
# =============================================================================

    # YOUR CODE HERE
    pass
