Python codecs Module
Example
Encode and decode text with a specific codec:
import codecs
data = "Emil"
b = codecs.encode(data, "utf-8")
print(b)
print(codecs.decode(b, "utf-8"))

Definition and Usage
The codecs module provides stream and file interfaces for transcoding data, plus codec lookup and registration.
Use it to work with specific encodings, wrap files with encoders/decoders, and register custom codecs.
