x substring 0 1  Details substring start  end   extracts the characters from a string  between the 2 indices  quot start quot  and  quot end quot   not including  quot end quot  itself  Special notes  If  quot start quot  is greater than  quot end quot   this method will swap the two arguments  meaning str substring 1  4     str substring 4  1   If either  quot start quot  or  quot end quot  is less than 0  it is treated as if it were 0
