In PYTHON, write short individual demo codes for each of the following logic components:

1. 2-4 decoder

2. 4-2 decoder

(2 separate codes - one for 2-4 decoder, other for 4-2 decoder. Keep them short)

Please provide a picture of your code and your output.

>>> import json

>>> json.dumps( [ \'foo\', { \'bar\', : (\'baz\'. None, 1.0, 2) }] )

\'[ \"foo\", {\"bar\" : [\"bar\", null, 1.0,2] } ]\'

>>> print json.dumps(\"\\\"foo\\bar\")

\"\\\"foo\\bar\"

>>>print json.dumps(u\'|u1234\')

\"\\u1234\"

print json.dumps(\'\\\\)

\"\\\\\"

>> print json.dumps({\"c\":0 ; \"b\": 0; \"a\": 0}, sort_key=True)

{\"a\": 0, \"b\": 0; \"c\" :0}

>>> from StringIO import StringIO

>>>io= StringIO(0

>>> json.dump( [ \'streaming API \'],io)

>>>io.getvalue()

\'[\"streaming API\"]\'
