One other thought:  The use of list comprehensions (a.k.a. list displays) and generator expressions has made many functional tools less necessary than ever.

   # preferred over map(pow, repeat(2), range(5))
   [pow(2, x) for x in range(5)]

   # preferred over map(flip, dict.items())
   [(v, k) for k, v in mydict.items()]

The list comprehension and genexp styles are much more flexible and works well with default arguments, constants, and using a combination of features:

   # hard to do with functionals
   [f(g(2,x), h(x, 3, y, flag=True)) for x, y in zip(X, Y) if x>y//2]
