jq for pythonista

jq is too difficult

jq is too difficult, at least for me.

For example, extracting key-name when use is true only, from below JSON data.

{
  "apps": {
    "foo": {
      "use": true
    },
    "bar": {
      "use": true
    },
    "boo": {
      "use": true
    },
    "bee": {
      "use": false
    }
  }
}

What is jq’s answer? (taking over 30 minutes, my past challenges).

$ cat data.json | jq -r '.apps | . as $$o | keys | map(select($$o[.].use))'
[
  "bar",
  "boo",
  "foo"
]

If you have python’s knowledge, this is tiny oneliner, isn’t it?

$ cat data.json | jqfpy '[k for k, opts in get("apps").items() if opts["use"]]'
[
  "foo",
  "bar",
  "boo"
]

(get() is special function, like a json.load(sys.stdin).get.)
