The wonderful uses of python encode and decode

String decoding:

There is a string:

'\u4fee\u6539\u8282\u70b9\u72b6\u6001\u6210\u529f'

Want to convert to:

u"u4feeu6539u8282u70b9u72b6u 6001u6210u529f"

can be passed as follows

>> a = '\u4fee\u6539\u8282\u70b9\u72b6\u6001\u6210\u529f'

>>> a.decode('unicode_escape')

u'u4feeu6539u8282u70b9u72b6u6001u621 0u529f'

string converted to 16 Base:

>>> "hello".encode("hex")

'68656c6c6f'

The corresponding one is OK

>>> '68656c6c6f'.decode("hex")

'hello'
