運行程序錯誤提示：

UnicodeDecodeError

UnicodeDecodeError: ’ascii’ codec can’t decode byte 0xef in position 16: ordinal not in range(128)

就是有中文的這一行出錯了，請問怎么處理呢

問題解答

報錯應(yīng)該是你python程序那邊報吧, 試下把你python那邊的中文編碼處理下, 或者試下全部用unicode吧, 參考下面:

with open(’test_%s.html’ % date, ’w’) as f:f.write(a.render( {’date’: date,’total’: 30,’title’: u’報告’ % date, u’project_list’: project_info }).encode(’utf8’))
