how to plot the FFT of a list of values

I have 16 values of the period sequence 1, 2, 4, 8, 1, 2, 4, 8, ... I compute its fourier transform using >>> from scipy import fft, ifft >>> x = [1,2,4,8,1,2,4,8] >>> fft(x) array([ 30. +0.j, 0. +0.j, -6.+12.j, 0. +0.j, -10. +0.j, 0. +0.j, -6.-12.j, 0. +0.j]) Now how can I plot
