Changes in getting started with list. Elaborating some points as suggested in review
from scipy import linspace, pi, sin
from pylab import plot, legend, show, title
from pylab import xlabel, ylabel
x = linspace(-2*pi,2*pi,100)
plot(x,sin(x))
legend(['sin(x)'])
title('Sine plot')
xlabel('x')
ylabel('sin(x)')
show()
