Dunno if the performance of this solution is good and if it is more
readable then RegExps, but here is LC:
[x for x in l if not [j for j in junkList if x.lower().find(j) > -1]]
>>> l = ["My skull hurts", "Drive the thruway", "Interchangability is
not my forte"]
>>> junkList =["interchange", "ifferen", "thru"]
>>> [x for x in l if not [j for j in junkList if x.lower().find(j) > -1]]
['My skull hurts', 'Interchangability is not my forte']
^ Is there an "e" missing?
Because I don't like RegExps! ;-)
