Mi código:

#define  lightSegments ;
{
{ { { { const int pins[7] = {2, 3, 4, 5, 6, 7, 8 };

    const byte numbersDisplayAnode[10] =
    { 0b1000000,   //0;

This is the English section for bootloader and uploading issues.
There are about 13 bugs in your sketch, I marked them with // ?
You have not replied to the answers in your previous question.

you´re right I'm in another section

Too many {s and }s.

This compiles without error or warning and should display the digits 0 through 9 repeatedly on the seven-segment display connected to pins 2 through 8.

const int pins[7] = {2, 3, 4, 5, 6, 7, 8 };

const byte numbersDisplayAnode[10] =
{
  0b1000000,   //0;
  0b1111001,   //1;
  0b0100100,   //2;
  0b0110000,   //3;
  0b0011001,   //4;
  0b0010010,   //5;
  0b0000010,   //6;
  0b1111000,   //7;
  0b0000000,   //8;
  0b0010000,   //9;
};

void  setup()
{
  for (int i = 0; i < 7; i++)
  {
    pinMode(pins[i], OUTPUT);
  }

  // Display 0 on the seven-segment display.
  lightSegments (0) ;
}

void loop()
{
  // Display 0 through 9 on the seven-segment display.
  for (int i = 0; i < 10; i++)
  {
    lightSegments(i);
    delay(1000);
  }
}

// Display a digit on the seven-segment display.
// WARNING: 'number' must be 0 through 9 only.
void lightSegments(int number)
{
  // Get the pattern of segments from the lookup table
  byte numberBit = numbersDisplayAnode[number];

  // Dispay the pattern on the seven segments
  for (int i = 0; i < 7; i++)
  {
    int bit = bitRead(numberBit, i);
    digitalWrite(pins[i], bit);
  }
