Python: Bytes to string giving escape characters-CodePudding

rmsg variable is bytes. Value is:

rmsg = [{"Id": "A1", "status": "P", "message": ""},
        {"Id": "A2", "status": "F", "message": ""}]

I want to convert it to string so as to pass it to JSON message. I am using below command to convert it to string.

rmsg = rmsg.decode("utf-8")

Using below command to create JSON:

rjson = {"Response Message": rmsg}

JSON message=

{
    "Response Message": "[{\"Id\": \"A1\", \"status\": \"P\", \"message\": \"\"}, {
\"Id\": \"A2\", \"status\": \"F\", \"message\": \"\"}]\n"
}

But Im getting escape character: \n at the end. I dont want to use strip command to remove it. Any other ways to pass bytes to JSON string without dealing with escape chararcters?

CodePudding user response：

In case you need to keep the JSON as a string, you can do the next:

rmsg = json.dumps(json.loads(rmsg.decode('utf-8'))

It will load data from JSON string and then dump it again to a string, but in one line, so no \ns etc.

But probably what you really want is to have the JSON stored as a dict/lists. In this case, you can do the next:

rmsg = json.loads(rmsg.decode('utf-8')
rjson = {"Response Message": rmsg)

Update: In case the original rmsg can contain a valid JSON or just a string, you should handle this (through exceptions handling). For example:

rmsg = rmgs.decode('utf-8')

try:
    rmgs = json.loads(rmsg)
except JSONDecodeError:
    pass
