# Variables and Data Types Example
name = "Alice"        # String
age = 25             # Integer
height = 5.6         # Float
is_student = True    # Boolean
hobbies = ["reading", "coding", "gaming"]  # List

print(f"Name: {name}, Age: {age}")
print(f"Height: {height}, Student: {is_student}")
print(f"Hobbies: {hobbies}")
