# EXERCISE 2: In this exercise you'll use an existing function, and while adding your own to create a fully functional
# program from the commented information.
# 1) Add a function named list_benefits() that returns the following list of strings: "More organized code", "More
# readable code", "Easier code reuse", "Allowing programmers to share and connect code together"
# 2) Add a function named build_sentence(info) which receives a single argument containing a string and returns a
# sentence starting with the given string and ending with the string " is a benefit of functions!"
#
# 3) Run and see all the functions work together!

# Modify this function to return a list of strings as defined above
# def list_benefits():
#     pass
#
# # Modify this function to concatenate to each benefit - " is a benefit of functions!"
# def build_sentence(benefit):
#     pass
