Feature Request: generator.send

[GoogleCodeExporter]

Code you're trying to run:

def mygen(upto):
    for i in range(0, upto):
        print 'i',i
        got = yield i
        print 'got',got

handle = mygen(3)
first = True
for num in handle:
    print 'num',num
    if first:
        print 'signalling'
        foo = handle.send('sig')
        print 'foo', foo
        first = False

What does "real" Python output?

i 0
num 0
signalling
got sig
i 1
foo 1
got None
i 2
num 2
got None

Note that .send(value) also advances the generator (something I'd not 
previously realised)

What browser are you using? On what operating system?
Firefox 3.6.15, Ubuntu Maverick (10.10)

Please provide any additional information.

As far as I know this is not yet implemented in Skulpt, but was added to python 
in 2.5.

Thanks for the report. Fixed at head, but not on skulpt.org yet.

generator.throw/close are bit more tricky so haven't done those yet. If you 
need those please feel free to open another issue (though they'll take a bit 
more time to get to).

awesome, thanks, having throw & send would be nice, but I don't think essential 
for what I'm doing.
