### Max split
Python's split method takes a maxsplit argument which limits the number of splits, so that, for example, `"the quick brown fox".split(" ",2)` would result in `["the","quick","brown fox"]`. Qt does not have such a feature, though it is easily implemented.
This snippet based on answer from https://stackoverflow.com/questions/18343253/qt-qstring-maxsplit-argument
```plaintext
QStringList split_with_max(QString& str, QString& sep, int maxSplit=-1)
{
  if( maxSplit < 0 ) return str.split(sep);
  if( maxSplit == 0 ) return QStringList(str);
  QStringList list = str.split(sep).mid(0, maxSplit);
  QString remainingStr = str.section(sep, maxSplit);
  list << remainingStr;
  return list;
}
```

### Printing to console
```plaintext
QTextStream& qStdOut()
{
    static QTextStream ts( stdout );
    return ts;
}

QTextStream& qStdErr()
{
    static QTextStream ts( stderr );
    return ts;
}

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    QDir dir;

    qStdOut() << dir.currentPath() << "\n";
    qStdOut().flush();
}
```
