'UnicodeEncodeError：'ascii'codec'尝试使用python将£sign写入excel表时出错

Question

我在python中抓取一个£值，当我尝试将它写入excel表时，进程中断，我得到以下错误

UnicodeEncodeError：'ascii'编解码器无法对位置0中的字符u'\ xa3'进行编码：序数不在范围内（128）

£符号在cmd提示符下打印时没有任何错误。有人可以建议我如何将价值（£1,750）写入我的表格（有或没有£符号）。非常感谢...

Answer 1

您需要明确地将unicode对象编码为字节。否则，您的系统将自动尝试使用ascii编解码器对其进行编码，该编解码器将使用非ascii字符进行编码。所以，这个：

Rateable_Value = Rateable_Value.encode('utf8')

之前

writer.writerow([Rateable_Value])

应该做的伎俩。
