is there a pythonic way to try something up to a maximum number of times? [duplicate]

Answer 1

1.Definition:

def try_three_times(express):
    att = 0
    while att < 3:
        try: return express()
        except: att += 1
    else: return u"FAILED"

2.Usage:

try_three_times(lambda: do_some_function_or_express())

I use it for parse html context.
