我是python的初学者。我无法理解问题是什么?
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()
我得到的错误是:
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'
