比较列表与python中的元组

>>> L1 = [\"the\",\"end\"]
>>> bigramslist = [ (\"the\",\"end\"), (\"end\",\"of\"), (\"of\",\"the\"), (\"the\",\"world\") ]
>>> tuple(L1) in bigramslist
True

>>> bigramsset = set( [ (\"the\",\"end\"), (\"end\",\"of\"), (\"of\",\"the\"), (\"the\",\"world\") ] )
>>> L1 = [\"the\",\"end\"]
>>> tuple(L1) in bigramsset
True

>>> list = [\"the\", \"end\"]
>>> bigramslist = [ (\"the\", \"end\"), (\"end\", \"of\"), (\"of\", \"the\"), (\"the\", \"world\") ]
>>> def check(list, biglist):
...     return [(list[0], list[1]) == big for big in biglist]
... 
>>> check(list, bigramslist)
[True, False, False, False]
