### Codec APIs
|
||
|
|
|
||
|
|

|
|
def encode(self,input,errors='strict'):

### encodings module API

### Decoding Map
|
||
|
|
|
||
|
|
decoding_map = codecs.make_identity_dict(range(256))
|
||
|
|
decoding_map.update({

|
||
|
|
"abc": 0x0078,
|
||
|
|
})

|
|
|
||
|
|
### Encoding Map
|
||
|
|
|
||
|
|
encoding_map = {}
|
||
|
|
for k,v in decoding_map.items():
|
||
|
