Made changes to script, getting started with arrays, as suggested in internal 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()
