将多个json文件合并为一个python

Question

I am trying to merge multiple json file into one that looks like this:

file1: [[a,b],[c,d],[e,f]]
file2: [[g,h],[i,f],[k,l]]
file3: [[m,n],[o,p],[q,r]]

I am using this code to merge the files:

data = []
for f in glob.glob("*.json"):
    with open(f,) as infile:
        data.append(json.load(infile))

with open("merged_file.json",'w') as outfile:
  json.dump(data, outfile)

out:  [[[a,b],[c,d],[e,f]],[[g,h],[i,f],[k,l]],[[m,n],[o,p],[q,r]]]

But what I really need is this:

[[a,b],[c,d],[e,f],[g,h],[i,f],[k,l],[m,n],[o,p],[q,r]]

Instead of having separated lists, I need all the pairs in one list.

Hope someone can help me, cheers!

Answer 1

If you are sure all files become list s after json.load -ing you might replace:

data.append(json.load(infile))

with

data.extend(json.load(infile))

Which should produce desired result.
