New submission from Mark Bell:
The built-in function sum takes an optional argument "start" to specify what
value to start adding from (defaults to 0). This argument should be a keyword
argument in order to match the other built-in functions such as:
enumerate(range(10), start=5)
This patch allows users to write:
sum(range(10), start=5)
which previously raised "TypeError: sum() takes no keyword arguments". Since
the only change is making an optional positional argument into a keyword
argument, this has no effect on any existing code using the current convention
of:
sum(range(10), 5)
