運(yùn)行程序錯(cuò)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(cuò)了，請(qǐng)問(wèn)怎么處理呢

問(wèn)題解答

報(bào)錯(cuò)應(yīng)該是你python程序那邊報(bào)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(bào)告’ % date, u’project_list’: project_info }).encode(’utf8’))
