Because there is just one right way to do it:
"".join([str1, str2, str3, ...])
Summing involves use of the repeated adds which
is terribly inefficient for strings. But, if you must:
reduce(str.__add__, [str1, str2, str3, ...], '')
Besides, it's very nice to be able to specify the join
character or blank.

Nope, it's is just a bad idea.
