Merge JSON Files

[Ugo]

I want to incrementally merge multiple json files of similar structure into a single file that already exists.

My code is:

import glob

read_files = glob.glob("/dbfs/mnt/sourton-house/File*.json")
with open("/dbfs/mnt/sourton-house/mergedJsonFile.json", "w") as outfile:
    outfile.write('{}'.format('\n'.join([open(f, "r").read() for f in read_files])))

The problem is that it over-writes mergedJsonFile.json. I want the files to merge into mergedJsonFile.json
