wish of those help I'm currently trying to get my code to write data to file exactly the way it prints it. ,
when I open the textfile afterwards there is only binary data.
code :
   fwrite(&x,1,sizeof(float),datei);
   ..
   fwrite(&y,1,sizeof(float),datei);
fprintf(datei, "%f\t%f\n", x, y);

may help you . I use the following code to write strings to my simple text file: , This is a complete example on how to solve your problem:
code :
      import java.io.BufferedReader;
      import java.io.BufferedWriter;
      import java.io.File;
      import java.io.FileReader;
      import java.io.FileWriter;
      import java.io.IOException;
      import java.util.HashSet;

      public class HisSaver {
        private HashSet<String> uniqueTester = new HashSet<String>();

        private String fileLocation="/mnt/sdcard/out.txt";

        private static HisSaver instance = null;


        private HisSaver() {
            readWordsFromFile();
        }

        public static HisSaver getInstance() {
            if(instance == null)
                instance = new HisSaver();
            return instance;
        }

        public void saveWord(String word) {
            if(!uniqueTester.contains(word)) {
                uniqueTester.add(word);
                writeWordToFile(word);
            }
        }

        private void writeWordToFile(String word) {
          try {
               BufferedWriter bw = new BufferedWriter(new FileWriter(new File(
                       fileLocation), true));
               bw.write(word);
               bw.newLine();
               bw.close();
          } catch (IOException e) {

          }
        }

        private void readWordsFromFile() {
          try {
            BufferedReader br = new BufferedReader(new FileReader(new File(
                fileLocation)));
            String line;
            while((line = br.readLine()) != null) {
                if(!uniqueTester.contains(line)) {
                    uniqueTester.add(line);
                }
            }
          } catch (IOException e) {

          }
        }
      }
    HisSaver hs = HisSaver.getInstance();
    hs.saveWord("newWord");

I hope this helps . Here are two modern methods to echo into a file without trailing spaces:
Note the first redirection only has one > to create or overwrite the file.
code :
@ECHO OFF

SET v1old=4
SET v2old=0
SET v3old=7453
SET v1new=83
SET v2new=645
SET v3new=2
SET bug=SET

 >newupdate.bat ECHO @ECHO OFF ^& SETLOCAL
>>newupdate.bat ECHO REM .
>>newupdate.bat ECHO REM version von dolphin
>>newupdate.bat ECHO %bug% v1old=%v1new%
>>newupdate.bat ECHO %bug% v2old=%v2new%
>>newupdate.bat ECHO %bug% v3old=%v3new%
ECHO %bug% bug=%bug%

PAUSE
EXIT
@ECHO OFF

SET v1old=4
SET v2old=0
SET v3old=7453
SET v1new=83
SET v2new=645
SET v3new=2
SET bug=SET

(
ECHO @ECHO OFF ^& SETLOCAL
ECHO REM .
ECHO REM version von dolphin
ECHO %bug% v1old=%v1new%
ECHO %bug% v2old=%v2new%
ECHO %bug% v3old=%v3new%
)>newupdate.bat
ECHO %bug% bug=%bug%

PAUSE
EXIT

will help you You can use the append 'a' modifier when you open a file to write where you left off. For example:
code :
outfile = open('Accounts_Details.csv', 'a')
for key, value in sorted(data.items()):
    outfile.write('\t' + str(value) + '\n')

it helps some times Your error on b = a.split("\n\n") is because you seem to think that f.writelines() will return something. It doesn't, so a has the value None and can't be split.
The documentation says this about what writelines() does:
code :
recognized_text = r.recognize_google(audio)
remainder = recognized_text.split()
while remainder:
    line, remainder = remainder[:5], remainder[5:]
    f.write(' '.join(line) + "\n")

To fix the issue you can do I'm using Python 2.7 and trying to read from pipe-delimited Src file, adding string to each line and writing the string to another file.
code :
line1 = line.rstrip() + "|key|false\n"
