Good idea, sometimes. On the opposite end, I will sometimes go out of my way to name something when there isn't an immediately apparent need. Also naming can often shorten up a long line. Trivial example: In [15]: SortByLen = lambda x: len(x) In [16]: SortByLast = lambda x: x[-1] In [17]: listOfInterest = ['123', '234', '432''12', '12345', '123'] In [18]: sorted(listOfInterest, key=SortByLen) Out[18]: ['123', '234', '123', '43212', '12345'] In [19]: sorted(listOfInterest, key=SortByLast) Out[19]: ['43212', '123', '123', '234', '12345']
