Ah... true enough.  That was too trivial an example to be meaningful.

I should have written:

----------
# least efficient
result = ''
for item in some_list:
    result += do_something(item)
return result

# more efficient
result = []
for item in some_list:
    result.append(do_something(item))
return ''.join(result)

# most efficient
''.join([do_something(item) for item in some_list])
----------
