[fontsize=\relsize{-2},numbers=left]>>> x = [5,12,13,200]>>> x[5, 12, 13, 200]>>> x.append(-2)>>> x[5, 12, 13, 200, -2]>>> del x[2]>>> x[5, 12, 200, -2]>>> z = x[1:3] # array "slicing": elements 1 through 3-1 = 2>>> z[12, 200]>>> yy = [3,4,5,12,13]>>> yy[3:] # all elements starting with index 3[12, 13]>>> yy[:3] # all elements up to but excluding index 3[3, 4, 5]就是不太明白中括號里的冒號是對X集合做什么處理，請賜教裝過，都成功運行編寫程序）
