Question

I’ve just started learning Python a few hours ago, and there seems to be a problem that I simply can’t seem to get.

They ask me to:

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!

I’ve googled this question, but all of them seem to be for previous versions of python, I was hoping for an updated way to do this.

Given Code:

def name_the_benefits_of_functions():
    list_of_benefits = list_benefits()
    for benefit in list_of_benefits:
        print build_sentence(benefit)

name_the_benefits_of_functions()

Expected output:

More organized code is a benefit of functions!
More readable code is a benefit of functions!
Easier code reuse is a benefit of functions!
Allowing programmers to share and connect code together is a benefit of functions!

What I have tried:

def list_benefits():
    benefits_list = ["More organized code", "More readable code", "Easier code reuse",           "Allowing programmers to share and connect code together"]
    return benefits_list
def build_sentence(benefit):
    return "%s is a benefit of functions!" % list_benefits()

def name_the_benefits_of_functions():
    list_of_benefits = list_benefits()
    for benefit in list_of_benefits:
        print(build_sentence(benefit))

name_the_benefits_of_functions()

Output:

['More organized code', 'More readable code', 'Easier code reuse', 'Allowing programmers to share and connect code together'] is a benefit of functions!
['More organized code', 'More readable code', 'Easier code reuse', 'Allowing programmers to share and connect code together'] is a benefit of functions!
['More organized code', 'More readable code', 'Easier code reuse', 'Allowing programmers to share and connect code together'] is a benefit of functions!
['More organized code', 'More readable code', 'Easier code reuse', 'Allowing programmers to share and connect code together'] is a benefit of functions!

Could anyone tell me what I’m doing wrong?

Answer 1

Each time you call the build_sentence() function, you only want it to build a sentence using a single benefit, which you specify in its benefit argument.

def build_sentence(benefit):
    return "%s is a benefit of functions!" % benefit

For each iteration of this loop:

for benefit in list_of_benefits:
    print(build_sentence(benefit))

a single benefit is passed to the build_sentence() function, and that’s what you want to print.
