New submission from Bernhard Reiter:
http://docs.python.org/3.4/library/xmlrpc.client.html as of 2013-06-19 20:35 UTC
has a divide example and the output can misslead the learning reader
towards the new behaviour of python3 with the '/' binary operator for division.
server code:
def divide(x, y):
return x/y
client code:
multicall.divide(7,3)
[..]
print("7+3=%d, 7-3=%d, 7*3=%d, 7/3=%d" % tuple(result))
The client call results into:
python3 client.py
7+3=10, 7-3=4, 7*3=21, 7/3=2
This is missleading because '7/3' is now resulting to a float in python3 (see
PEP238).The example probably was copied over from the python2 documentation
where '7/3' result to int. The implicit conversion from float to int is done
in the string formatting.
Proposal replace the print line with
print("7+3=%d, 7-3=%d, 7*3=%d, 7/3=%g" % tuple(result))
to get
7+3=10, 7-3=4, 7*3=21, 7/3=2.33333
or
print(repr(tuple(result)))
to get
(10, 4, 21, 2.3333333333333335)
