# 5.1 Functions
# A. Write a function that accepts one parameter, name
# The function should print the message "Hello, _____." filling in the blank with the name
def anyone(name):
return f'Good morning, {name}.'

# B. Write a function that accepts one parameter, a number
# The function should return true or false depending on whether the number is even
def even(number):
return number % 2 ==0
print(even(15))

# C. Write a function that accepts one parameter, a list
# The function should return the sum total of all numbers in the list, using a loop
def lista(numbers):
return sum(numbers)
lista([1,3,5,7,9,11])
# D. Write a function that accepts one parameter, a dictionary
# The function should print the message "Introducing ______ ______, ________!"
# Fill in the blanks with the "first_name", "last_name", and "title" properties of the dictionary
def diccionario(dict):
return print(f'Introduciendo {dict["first_name"]} {dict["last_name"]}, {dict["title"]}!')
