This uses repr() to display the result
print(sum(s))
1.0 Why?
This uses str() to display the result.
In many cases str() calls repr() but in other cases str() is a more
user
friendly format. repr() tends to be a developers eye view of things.
This is one reason that in my tutorial I always use print() to display
results. The output is more newbie friendly that way :-)
I suspect the details will be revealed by a search for documentation
on __repr__
