AttributeError: 'tuple' object has no attribute

Question

I'm a beginner in python. I'm not able to understand what the problem is?

def list_benefits():          s1 = "More organized code"         s2 = "More readable code"         s3 = "Easier code reuse"         s4 = "Allowing programmers to share and connect code together"         return s1,s2,s3,s4  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() 

The error I'm getting is:

Traceback (most recent call last):    Line 15, in <module>    print build_sentence()    Line 11, in build_sentence    print obj.s1 + " is a benefit of functions!" AttributeError: 'tuple' object has no attribute 's1' 

Answer 1

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!"
