python字符串unicode问题

Question

这是我的代码(我使用的是 python 2.7)

    result = " '{0}' is unicode or something: ".format(mongdb['field'])
UnicodeEncodeError: 'ascii' codec can't encode character u'\xb0' in position 27: ordinal not in range(128)

看起来我从 mongodb 读取的字符串包含 unicode。它抛出这个错误。如何修复它以将此 unicde 与自定义字符串“is unicode or something:”连接起来？

提前致谢

更新

result = u" '{0}' is unicode or something: ".format(mongdb['field']) 

对我有用

Answer 1

使用unicode格式字符串(推荐):

result = u" '{0}' is unicode or something: ".format(mongdb['field'])

或者对字段进行编码:

result = " '{0}' is unicode or something: ".format(mongdb['field'].encode('utf-8'))
