Generate JSON file from file names and their content

Question

I'm new to python, and couldn't find a close enough answer to make me figure it out. I'm trying generate a single json file that contains current directory file names that end with a .txt extension as nodes, and the contents of those files as a list inside the file name's node.

for example:

node1.txt contains

foo
bar

and node2.txt contains

test1
test2

the output should look like:

{
  "node1": [
     "foo",
     "bar"
   ],
   "node2": [
     "test1",
     "test2"
   ]
}

You should provide your best attempt(s), so we can see where you are actually stuck. — 9769953

As a starting point I suggest you take a look at the glob module docs.python.org/3/library/glob.html — user2668284

you need to learn 1) how to read a file. 2) how to generate json. 3) how to write to a file. These are what you should be asking yourself. Rather than asking for an end to end solution. — Mark

Use pathlib and json modules and a simple loop...

import pathlib
import json

data = {}
for node in pathlib.Path('.').glob('node*.txt'):
    with open(node, 'r') as fp:
        data[node.stem] = [line.strip() for line in fp.readlines()]

print(json.dumps(data, indent=4))

Output:

{
    "node1": [
        "foo",
        "bar"
    ],
    "node2": [
        "test1",
        "test2"
    ]
}
