如何从 odoo10 中的 unicode[u'a', u'd'] 获取字段值

Question

我想得到字符串形式的 unicode。为此，我的代码在这里：

@api.multi

    def _select_service_product(self):

        r = []

        for order in self.order_line:

            res = order.product_id.type_service

            r.append(res)

            self.services_infor = r

            l = self.services_infor

            print "test,,,", res, self.services_infor, l

services_infor = fields.Char(compute='_select_service_product')

现在终端显示：

test,,, d [False, u'a', u'd'] [False, u'a', u'd']

从这里我想要值 a，b

Answer 1

x = u"['a', 'b']"
# either you c an explicitly convert the unicode chars
print str(x)
output : "['a', 'b']"
#use eval function to make the unicode list to original
print eval(x)
output: ['a','b']
