Python: Convert dictionary to bytes

You can use indent option in json.dumps() to obtain \n symbols:

import json

user_dict = {'name': 'dinesh', 'code': 'dr-01'}
user_encode_data = json.dumps(user_dict, indent=2).encode('utf-8')
print(user_encode_data)

Output:

b'{\n  "name": "dinesh",\n  "code": "dr-01"\n}'

You can use Base64 library to convert string dictionary to bytes, and although you can convert bytes result to a dictionary using json library. Try this below sample code.

import base64
import json


input_dict = {'var1' : 0, 'var2' : 'some string', 'var1' : ['listitem1','listitem2',5]}

message = str(input_dict)
ascii_message = message.encode('ascii')
output_byte = base64.b64encode(ascii_message)

msg_bytes = base64.b64decode(output_byte)
ascii_msg = msg_bytes.decode('ascii')
# Json library convert stirng dictionary to real dictionary type.
# Double quotes is standard format for json
ascii_msg = ascii_msg.replace("'", "\"")
output_dict = json.loads(ascii_msg) # convert string dictionary to dict format

# Show the input and output
print("input_dict:", input_dict, type(input_dict))
print()
print("base64:", output_byte, type(output_byte))
print()
print("output_dict:", output_dict, type(output_dict))
