Python 3 - The Quirky Starmap Function

In this session we'll look at the rather interesting starmap function, from the itertools module.

It is worth mentioning that STARmap name is referring to unpacking operator(*). To show how it works (and where the name starmap came from) we can create 3rd version of results:
def pow2(i):
return pow(*i)

results_v3 = map(pow2, nums)

I see no reason to use the starmap function. It all can be done with (the more powerful) list comprehension. Is it not in the contrary to the Zen of Python? ("There should be one - and preferably only one - obvious way to do it.")

list(starmap(perimeter, measurements))

[starmap(lambda name, num: (name + ' ') * num, for name, num in names]

vs:

[perimeter(*x) for x in measurements]

[(lambda name, num: (name + ' ') * num)(*x) for x in names]
