Why is following code not producing any result? Why is it giving errors?

Q. Why is following code not producing any result? Why is it giving errors?

(Note. All required libraries have been imported and are available)

a = range (10, 50, 12)
b = range (90, 200, 20)
matplotlib.pyplot.plot(a, b)

Answer :-

The above code is producing error because the two sequences being plotted i.e., a and b do not match in shape. While sequence 'a' contains 4 elements, sequence 'b' contains 6 elements. For plotting, it is necessary that the two sequences being plotted must match in their shape.
