I expected this to be fixed in Python 3:
sum(['ab','cd'],'')
Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: sum() can't sum strings [use ''.join(seq) instead]
Of course it is not a good way to join strings, but it should work, should it not? Naturally,
'' + 'ab' + 'cd'
'abcd' Why doesn't duck typing apply to `sum`? Thanks, Alan Isaac -- http://mail.python.org/mailman/listinfo/python-list
