Append extension to output of os.environ.get

I'm new to python and I'm trying to create a json file named after an environment variable.

The variable is called parent with the value galaxy

This is what my file looks like.

import json
import sys
import os

Report = os.environ.get('MainReport')

if Report == "Main":
    newFile = os.environ.get('parent')
else:
    newFile = os.environ.get('child')

#####Additional Logic Here############

json_output = json.dumps(output,indent=4)
with open(newFile, "w") as outfile:
    outfile.write(json_output)

print("Output file is generated in the current directory!")
file.close()

When I run the script, it creates the file galaxy in my current directory as expected.

But I need the file to be named galaxy.json

I've tried

if Report == "Main":
    newFile = os.environ.get('parent').json

But it throws this error AttributeError: 'str' object has no attribute 'json'

Is there a way to append .json to the output from os.environ.get

Use the concatenation operator to append a string.

if Report == "Main":
    newFile = os.environ.get('parent') + ".json"
