如何在Python中进行以下转换？

Answer 1

将u'杭州'转换为'%BA%BC%D6%DD':

In [24]: ''.join('%{0:X}'.format(ord(c)) for c in u"杭州".encode('gbk'))
Out[24]: '%BA%BC%D6%DD'

In [25]: ''.join('%{0:X}'.format(ord(c)) for c in u"大连".encode('gbk'))
Out[25]: '%B4%F3%C1%AC'

将'%BA%BC%D6%DD'转换为u'杭州':

In [54]: import binascii    
In [55]: print(binascii.unhexlify(''.join('%BA%BC%D6%DD'.split('%'))).decode('gbk'))
杭州
