Loading a font from the system in pygame

I have a font called "pixelfont" that I would like to load onto my game. How can I load this font into pygame? I have tried the following method already:

    import pygame
    font_1_path = pygame.font.match_font("pixelfont", 0, 0)
    font_1 = pygame.font.Font(font_1_path, 128)
    text = font.render("Hello world!", True, (0, 0, 0))
    display.blit(text, [0, 0])

Why does this not print out "Hello world!" in pixelfont?
