# 1)Write a function called int_return that takes an integer as input and returns the same integer.

# Answer:

def int_return(n):
    return int(n)
print(int_return(2.5)) # This line is not needed


# 2) Write a function called add that takes any number as its input and returns that sum with 2 added. 

# Answer:

def add(n):
    return float(n + 2)
print(add(5.37)) # This line is not needed



# 3) Write a function called change that takes any string, adds “Nice to meet you!” to the end of the argument given, 
# and returns that new string.

# Answer:

def change(str):
    return str + "Nice to meet you!"

print("Hello, " + change("whatever your name is, ")) # This line is not needed



# 4) Write a function, accum, that takes a list of integers as input and returns the sum of those integers.

# Answer:

def accum(lst):
    lst_sum = 0
    for numbs in lst:
        lst_sum = lst_sum + numbs
    return lst_sum
    
lst = [1,2,3,4,10,6,7,8,9] # can be any list of numbers
accum(lst)
print(accum(lst)) # print is not needed



# 5) Write a function, length, that takes in a list as the input. If the length of the list is greater than or equal to 5, 
# return “Longer than 5”. If the length is less than 5, return “Less than 5”.

# Answer:

def length(lst):
    if len(lst) >= 5:
        return "Longer than 5"
    return "Less than 5" # can also use 'else:' but not needed in this case

lst1 = [1,2,3]
lst2 = [1, 2, 3, 4, 5]
lst3 = [1, 2, 3, 4, 5, 6]

print(length(lst1)) # 'print' are not needed
print(length(lst2))
print(length(lst3))




# 6) You will need to write two functions for this problem. The first function, 
# divide that takes in any number and returns that same number divided by 2. 
# The second function called sum should take any number, divide it by 2, and add 6. 
# It should return this new number. You should call the divide function within the sum function. 
# Do not worry about decimals.

# Anwer:

def divide(numb):
    return int(numb) // 2
    
def sum(numb):
    return int(numb) // 2 + 6

# Next 3 lines are not needed for this excersise
number = input("Enter any number:") # User input not needed
print(divide(number)) # print not needed
print(sum(number))
