python - join()转义的问题

Question

t = ['[', '"', '123', '"', ',"', 'haha', '"', ',"', '"', ',"', '**\\t', '"', ',"', '3709**********3125', '"', ',"', '', '"', ']']
print "".join(t)

>>> ["123","haha","","**\t","3709**********3125",""]

有什么办法可以让join返回的的时候不转义\,返回原始值么?

Answer 1

Can be used

'{!r}'.format(s)

Make s unescaped, ok for lists

t = list(map(lambda s:'{!r}'.format(s),t))

To handle it uniformly.
