• One parameter.
  
• Five lines (108 characters per line, 4 space indents).

def sierpinski(n):
    pascal = [[1]]
    for level in range(2 ** n - 1):
        pascal.append([1] + [sum(pair) for pair in zip(pascal[-1], pascal[-1][1:])] + [1])
    chars = [['A ' if number % 2 else '  ' for number in row] for row in pascal]
    [print(' ' * (2 ** n - row), ''.join(row_chars), sep = '') for row, row_chars in enumerate(chars)]

Output:
>>> sierpinski(4)
                A
               A A
              A   A
             A A A A
            A       A
           A A     A A
          A   A   A   A
         A A A A A A A A
        A               A
       A A             A A
      A   A           A   A
     A A A A         A A A A
    A       A       A       A
   A A     A A     A A     A A
