# HOMEWORK: Functions
# Read carefully until the end before you start solving the exercises.

# Basic Function
# Define a basic function that only prints Hello. Create the definition using def and the call that executes it.

def greeting(hi):
    print(hi)

greeting("Hello")

# ----------------------------------------------------------------------------------------------------------------------

# Basic Function with Parameters
# Define a basic function that prints a greeting taking a given name.


def greeting(greeting, name):
    print(greeting , name)


greeting("Hello", input("What is your name? "))
# ----------------------------------------------------------------------------------------------------------------------

# Basic Function with Default Values
# Define a basic function that prints a greeting for a name, but if none is given, use stranger instead of the name,
# so it behaves like this:

# Prints: Hello, stranger!
# greeting()

# Prints: Hello, Tom!
# greeting('Tom')


def greeting(greeting, name="stranger"):
    print(greeting, name)


greeting("Hello")
greeting('Hello', input("What is your name? "))

# ----------------------------------------------------------------------------------------------------------------------

# Multiple Parameters
# Define a function that takes two parameters, add them up and prints the sum.

# Prints: The sum of 1 + 2 = 3
# add(1, 2)

# Prints (default values might be useful): The sum of 1 + 0 = 1
# add(1)

def add(num1=0, num2=0):
    print(f"{num1} + {num2} = {num1 + num2}")

add(1, 2)
add(1)

# ----------------------------------------------------------------------------------------------------------------------

# Parameters out of order
# Define a function that takes a first_name and a last_name and prints a full_name. Define the function and create
# the function call in such a way that first_name and last_name can be given in any order and the printed full_name
# would still be correct.

# Prints: Nelson Mandela
# full_name("Nelson", "Mandela")

# Is there anything you can add to the line below, so the function also prints "Nelson Mandela"?
# full_name("Mandela", "Nelson")

def full_name(first='Nelson', last="Mandela"):
    print(f"{first} {last}")

full_name("Nelson", "Mandela")
full_name(last="Nelson", first="Mandela")

# ----------------------------------------------------------------------------------------------------------------------

# Returning Values
# Define a validator function that you can use to determine if a word is longer than 8 characters.
# After creating the function, make sure to test it. Create a list of words and iterate over this
# list using a for loop.

# Tip: Validator functions return True / False which we can use in conditionals to do things like print a message.

def less_than_eight(words):
   return True if len(words) < 8 else False

words = ["Happy", "Confident", "Toast", "Beauitfulll", "Together", "Cook"]


for char in words:
    if less_than_eight(char):
        print(f"{char} is less than eight letters")
    else:
        print(f"{char} more than eight letters")

# You're going to revisit some of the algorithms you've already solved. But this time, there's a twist! Your challenge
# is to solve and encapsulate each algorithm into its own Python function. This will not only help you review these
# algorithms but also give you valuable practice in defining and using functions.

# FizzBuzz
# You remember FizzBuzz, right?
# You print Fizz for multiples of 3, Buzz for multiples of 5, and FizzBuzz for multiples of both 3 and 5.

# Now, your task is to take your existing FizzBuzz code and wrap it into a function called fizzbuzz.

# Requirements:
# - Create a function named fizzbuzz that takes a single argument, number.
# - If the number is a multiple of both 3 and 5, the function should return: FizzBuzz
# - If the number is a multiple of 3, the function should return: Fizz
# - If the number is a multiple of 5, the function should return: Buzz
# - Otherwise, the function should return the number.

# Call the function here
def fizzbuzz(number):

    if number % 5 == 0 and number % 3 == 0:
        print("FizzBuzz")
    elif number % 5 == 0:
        print("Buzz")
    elif number % 3 == 0:
        print("Fizz")
    else:
        print(number)

fizzbuzz(int(input("Enter a number: ")))


# ----------------------------------------------------------------------------------------------------------------------

# Anagram
# Your next challenge is to implement a function that checks if two given strings are anagrams of each other.
# An anagram is a word or phrase formed by rearranging the letters of a different word or phrase. For example,
# "listen" is an anagram of "silent".

# What You Need to Check
# - The two strings must have the same length.
# - The sorted form of the first string must be equal to the sorted form of the second string.

# Approach
# - Create a function that takes two strings as arguments.
# - Check if the lengths are equal. If they're NOT equal, return False (anagrams are always same length).
# - Sort both strings. If the sorted versions are equal, they're anagrams!

# Test your function with these strings
def are_anagrams(str1, str2):
    if len(str1) != len(str2):
        return False

    return sorted(str1) == sorted(str2)


test_str1 = 'salo'
test_str2 = 'salo'

print(are_anagrams(test_str1, test_str2))
# ----------------------------------------------------------------------------------------------------------------------

# Find Max number
# Create a function to find the largest number in a list without using the built-in max() function.

# - Define a function called find_max that takes a list of numbers as an argument.
# - Initialize a variable result and set it to the 1st item of the list using [0]
#   - This variable will hold the largest number as we iterate through the list.
# - Loop through each number in the list.
# - Check if number > result
#   - If it is, update result with the new greater number.
# - return result

# Define your function here

# Test the function with a sample list of numbers.

# Output should be the maximum number in the list.
def find_max(numbers):
    result = numbers[0]


    for number in numbers:
        if number > result:
            result = number
            return result

list = [6, 99, 24, -23, 32]
print(find_max(list))

# ----------------------------------------------------------------------------------------------------------------------

# Even/Odd Checker Function
# Your task is to write a function that determines if a given integer is even or odd. The function should
# print Even for even numbers and Odd for odd numbers.

# What You Need to Check
# - Determine whether the input number is even or odd.
# - An even number can be exactly divided by 2 without a remainder.
# - An odd number leaves a remainder of 1 when divided by 2.

# Define a function is_even_odd(number) here

# Test the function calling it using a variety of numbers like: 1, 10, 5.5, 9

def is_even_odd(number):
    if number % 2 == 0:
        print(f"{number} is an even number")
    else:
        print(f"{number} is an odd number")

# Define the list of numbers
numbers = [1, 10, 5.5, 9]

# Loop through the list and call the function for each number
for num in numbers:
    is_even_odd(num)

In exercise Find Max number you should try a different solution because yours is returning the first number that's larger than the initial value, and not necessarily the biggest one.

Here's the corrected version of your code:

def find_max(numbers):
  max_value = numbers[0]
  for number in numbers:
    if number > max_value:
      max_value = number
  return max_value

list = [6, 99, 24, -23, 32]
print(find_max(list))
