[Python-ideas] a in x or in y

[Greg Ewing]

No language change required:

class either(object):

     def __init__(self, *args):
         self.args = args

     def __contains__(self, x):
         for a in self.args:
             if x in a:
                 return True
         return False

pocket = ['hankie', 'pocketknife', 'keys']
car = ['satchel', 'jacket', 'teddybear']

if 'keys' in either(car, pocket):
     print("Found them")
else:
     print("Lost them")
