class list benefits object       def   init   self           self s1    More organized code          self s2    More readable code          self s3    Easier code reuse   def build sentence            obj list benefits           print obj s1     is a benefit of functions           print obj s2     is a benefit of functions           print obj s3     is a benefit of functions    print build sentence     I know it is late answer  maybe some other folk can benefit If you still want to call by  attributes   you could use class with default constructor  and create an instance of the class as mentioned in other answers

You return four variables s1 s2 s3 s4 and receive them using a single variable obj  This is what is called a tuple  obj is associated with 4 values  the values of s1 s2 s3 s4  So  use index as you use in a list to get the value you want  in order   obj list benefits   print obj 0      is a benefit of functions   print obj 1      is a benefit of functions   print obj 2      is a benefit of functions   print obj 3      is a benefit of functions

Variables names are only locally meaningful   Once you hit  return s1 s2 s3 s4  at the end of the method  Python constructs a tuple with the values of s1  s2  s3 and s4 as its four members at index 0  1  2 and 3 - NOT a dictionary of variable names to values  NOT an object with variable names and their values  etc   If you want the variable names to be meaningful after you hit return in the method  you must create an object or dictionary
