If you ever want to find the sum of the values of an iterable without using a loop, then math.fsum() is probably the easiest way to do so. You can use iterables such as arrays, tuples, or lists as input and the function returns the sum of the values. A built-in function called...
@tannewt@andrewleechYes, I guess this is exactly the crux of this conversation. This whole goal of extending built-in modules is only really necessary to make an existing file work completely unmodified. In the "import foo_ext as foo" case, foo_ext still needs to do "from foo import *...
