Research direction
Start with the “Mutable and Immutable Types” section of the linked “Structuring Your Project” page and compare the existing example with the proposed expression. Done means the documentation uses the agreed example and presents any performance claim accurately.
Written by the indexing model from the issue text.
Description
The best example in the Mutable and Immutable Types section of the Structuring Your Project page is:
# create a concatenated string from 0 to 19 (e.g. "012..1819")
nums = [str(n) for n in range(20)]
print "".join(nums)
It is considered the best example for being both more efficient and succinct.
Would this be a better example to use?
''.join(map(str, range(20)))
It's more succinct and is faster:
$ python -m timeit "nums = [str(n) for n in range(20)]; ''.join(nums)"
100000 loops, best of 3: 6.84 usec per loop
$ python -m timeit "''.join(map(str, range(20)))"
100000 loops, best of 3: 4.93 usec per loop
