在Python中合并多个JSON文件的问题

在Python中合并多个JSON文件的问题

You can’t just concatenate two JSON strings to make valid
JSON
(or combine them by tacking

',n'

to the end of
each). Instead, you could combine the two (as Python objects) into a Python
list, then use

json.dump

to write
it to a file as JSON:

import jsonimport globresult = []for f in glob.glob("*.json"):    with open(f, "rb") as infile:        result.append(json.load(infile))with open("merged_file.json", "wb") as outfile:     json.dump(result, outfile)

---

If you wanted to do it without the (unnecesssary) intermediate step of parsing
each JSON file, you could merge them into a list like this:

import globread_files = glob.glob("*.json")with open("merged_file.json", "wb") as outfile:    outfile.write('[{}]'.format(        ','.join([open(f, "rb").read() for f in read_files])))
