with open('filename.txt', 'w') as file:
    long_string = "This is a long string that needs to be printed in a single line in the file."
    file.write(long_string)

import java.io.FileWriter;
import java.io.IOException;

public class Main {
    public static void main(String[] args) {
        try {
            FileWriter writer = new FileWriter("filename.txt");
            String longString = "This is a long string that needs to be printed in a single line in the file.";
            writer.write(longString);
            writer.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

using System.IO;

class Program
{
    static void Main()
    {
        string longString = "This is a long string that needs to be printed in a single line in the file.";
