If i want to use return here!! What would be the code for it

Question

def names(user):
for name in user:
print('Hello, ' + name.title())
username = names(['rohan', 'sunil', 'rahul'])

Answer 1

Given the list passed to the names() function, what should the variable username be? For instance do you just want them appended to each other so
username = "rohansunilrahul"
or some other result?
