尝试直到有效

Question

有没有办法在Python中执行以下操作？

try:
  Thing1()
try_this_too:
  Thing2()
try_this_too:
  Thing3()
except:
  print "Nothing worked :-("

请注意,如果Thing1()成功,我不想做任何其他事情.

Answer 1

for thing in (Thing1,Thing2,Thing3):
    try:
       thing()
       break  #break out of loop, don't execute else clause
    except:   #BARE EXCEPT IS USUALLY A BAD IDEA!
       pass
else:
    print "nothing worked"
