PYSNMP agent returns new line characters as output after decoding of Hexa values

Question

Facing a strange issue with the pysnmp agent return value. PYSNMP Agent receives the string format as "0a0a0a0a0a0a0a0a0a". In the MIB, OID is represented as HEXA STRING. When tried to return the string using rfc1902.OctetString(hexValue=str_temp), the output is blank because the hexavalue (0a0a0a) is decoded as new lines(\n) characters.

SNMPv2-SMI::example.154.12.1.0 = STRING: "

"

Pseudo code:

str="0a0a0a0a0a0a0a0a"
After Return using rfc1902.OctetString(str) or rfc1902.OctetString(hexaValue=str)

Excepted Output:

SNMPv2-SMI::example.154.12.1.0 = Hex-STRING: 0A 0A 0A 0A 0A 0A 0A 0A 

Can some one help me, how to decode or send the raw output to hexa string to get desired output as mentioned above.

    print(oid.prettyPrint(),' = ',val.prettyPrint())
