# Question 1
# Write a function to print "hello_USERNAME!" 
# USERNAME is the input of the function. 

def hello_username(user_name):
    """Function prints a given username"""
    print("\nHello_" + user_name.upper() + "!\n")

hello_username('username')#Call function


# Question 2
# Write a python function, first_odds 
# that prints the odd numbers from 1-100 
# and returns nothing

def first_odds():
    """Function prints odd numbers 1-100
    and returns none"""

        print(val, end="\n")
    return  #Will return 'None' in terminal

print(first_odds(), end='\n\n')#Call function


# Question 3
# Please write a Python function, max_num_in_list 
# to return the max number of a given list.

def max_num_in_list(a_list):
    """Function finds largest number in a list"""

max_num_in_list(a_list)#Call function


# Question 4
# Write a function to return 
# if the given year is a leap year. 
# A leap year is divisible by 4, 
# but not divisible by 100, 
# unless it is also divisible by 400. 
# The return should be boolean Type (true/false)

# Question 5
# Write a function to check to see 
# if all numbers in list are consecutive numbers. 
# For example, [2,3,4,5,6,7] are consecutive numbers, 
# but [1,2,4,5] are not consecutive numbers. 
# The return should be boolean Type
