will help you You could use json.dumps(your_dictionary, indent=2) to pretty print the json.
The json.dumps() method takes the python object and returns a JSON formatted string. The indent parameter is used to define the indent level for the formatted string.

How to set Line Spacing in UI Text View (Empty text view) to enter message with line space

help you fix your problem I had the same Problem. Based on Sergius answer I came up with the following working solution. The problem with Sergius answer was that all other already set attributes will be overwritten (Font, Color...)
So it is better to edit the existing typingAttributes:
code :
NSDictionary* d = deedTextView.typingAttributes;
NSMutableDictionary* md = [NSMutableDictionary dictionaryWithDictionary:d];
[md setObject:paragraphStyle forKey:NSParagraphStyleAttributeName];
deedTextView.typingAttributes= md;

fixed the issue. Will look into that further If I'm understanding you correctly, you can prevent users from inserting line breaks by pressing the Enter key by adding a listener. Something like this:
code :
var textarea = document.getElementById("myTextArea");
textarea.addEventListener("keydown", function (e) {
    if (e.keyCode == 13) { // keyCode 13 corresponds to the Enter key
        e.preventDefault(); // prevents inserting linebreak
textarea.addEventListener("paste", handler);

will help you I think I see the reason for your first two problems. When the KeyDown event runs you check for the Enter key, and if it was pressed you do your actions and clear textBox1. However, you still have not stopped the Enter key message from being passed onto the TextBox.
The fix is to set the e.SuppressKeyPress property to true which will cause the key press to not be passed to the TextBox, thus it won't add another new line in it.
code :
private void textBox1_KeyDown(object sender, KeyEventArgs e)
    if (e.KeyCode == Keys.Enter)
        textBox2.AppendText(textBox1.Text.TrimEnd() + "\n"); //TrimEnd() removes trailing white-space characters.
        textBox1.Text = "";
        e.SuppressKeyPress = true; //Do not pass the Enter key press onto the TextBox.

will help you try this use addTextChangedListener
code :
editText.addTextChangedListener(new TextWatcher() {
            public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {


            public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
                if (charSequence.toString().equals("")) {
                } else {

            public void afterTextChanged(Editable editable) {


I need a program that will ask the user to enter the information to save, line to line in a file. How can I do it?

this one helps. Well, you're almost there. First, I'd use a java.io.FileWriter in order to write the strings to a file.
It's not really necessary to use an array here if you just want to write the lines to a file.
code :
import java.io.*;
import java.util.Scanner;

public class Example {

    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);
        File f = new File("/tmp/output.txt");

        System.out.println("How many lines do you want to write? ");
        int mida = sc.nextInt();
        sc.nextLine(); // Consume next empty line

        try (FileWriter escriptor = new FileWriter(f)) {

            for (int i = 0; i < mida; i++) {
                System.out.println(String.format("Write line %d:", i + 1));
                String paraula = sc.nextLine();
                escriptor.write(String.format("%s\n", paraula));
        } catch (IOException e) {
