How to convert code from Java code to Python format T.T

The code below is the Java source code. I would like to see the code that converted this source code to Python format. (Due to lack of Python knowledge…)
Example) Data structure, instance creation Please help

        BufferedReader reader = new BufferedReader(new FileReader(file));
        BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(System.out));
        String s = "";
        Stack<Character> stack = new Stack<>();
        boolean flag = false;
        List<Jsoncolumn> result = new ArrayList<>();
        Answer answer = null;
        Questions questions = null;
        Jsoncolumn o = null;
        String lang="";
        boolean kycs=false;
        while ((s = reader.readLine()) != null) {
            for (char c : s.toCharArray()) {
                if (c == '{' || c == '[') stack.push(c);
                else if (c == ']' && stack.peek() == '[') stack.pop();
                else if (c == '}' && stack.peek() == '{') stack.pop();
            }
            if (stack.size()==1&&s.contains("level") && s.contains("NumberInt")) {
                flag = true;
                o = new Jsoncolumn();
                o.level = Integer.parseInt(s.replaceAll("[^0-9]", ""));
                System.out.println(o.level);
            }
            if(stack.size()==2){
                if (s.contains("kyc")&&!s.contains("s")) {
                    kycs=false;
                }
                if (s.contains("kycs")) {
                    kycs=true;
                }
            }

                        if(questions==null)questions=new Questions();

You already asked this in another topic, yesterday. It is rather rude to repost just because you didn’t get the answer written out completely for you.
