Question

我有一个地址列表，如果他们是美国或加拿大，则想举报。我有美国各州和CA Providences的列表。有没有更像红宝石的方式做到这一点：

us = false
address = '1234 Fake Address Ave N, Funtown, TX, 59595'
address = address.split(' ')
address.each do |part|
  if USStates.include? part
    us = true
  end
end

Answer 1

这里是一个班轮

address = '1234 Fake Address Ave N, Funtown, TX, 59595'
us = USStates.any? { |state| address.include?(state) }

    screen.fill(black)
    pygame.draw.rect(screen,white, move_rect ,0)

    # Move the rectangle, reverse direction at the sides
    if ( move_rect.left <= 0 or move_rect.right >= SCREEN_WIDTH-1 ):
        # Hit the sides: move down, change direction
        move_x *= -1           # change direction
