[FIXED] Yield an item with Python Bottle doesn't work

Issue

When using:

from bottle import route, run, request, view

N = 0

def yielditem():
    global N
    for i in range(100):
        N = i
        yield i

@route('/')
@view('index.html')
def index():
    print yielditem()
    print N    

run(host='localhost', port=80, debug=False)

the page index.html is successfully displayed, but the yield part is not working:

• N stays always at 0, for every new request

• print yielditem() gives <generator object yielditem at 0x0000000002D40EE8>

How to make this yield work normally in this Bottle Python context?

What I expect is: 0 should be printed at the first request, 1 should be printed at the second request, etc.

Solution

It looks you are printing the generator itself not its values:

from bottle import route, run, request, view

N = 0
def yielditem():
    global N
    for i in range(100):
        N = i
        yield i

yf = yielditem()

@route('/')
@view('index.html')
def index():
    print next(yf)
    print N    

run(host='localhost', port=80, debug=False)
