Question

Is there any way in Python to continue iterating after exception throwed by iterator/generator? Like in code below, is there any way to skip ZeroDivisionError and continue looping through gener() without modyfying run() function?

def gener():
    a = [1,2,3,4,0, 5, 6,7, 8, 0, 9]
    for i in a:
        yield 2/i

def run():
    for i in gener():
        print i

#---- run script ----#

try:
    run()
except ZeroDivisionError:
    print 'what magick should i put here?'

Answer 1

The logical place for the try/except would be the place where the offending calculation takes place:

def gener():
    a = [1,2,3,4,0, 5, 6,7, 8, 0, 9]
    for i in a:
        try:
            yield 2/i
        except ZeroDivisionError:
            pass
