Why the graph can not be plotted

Answer 1

Oliver Pasaribu
The graph needs to be save, just add plt.savefig('image.png') at the end.

Answer 2

The image needs to be saved in Sololearn in order to be displayed.
We need to use the savefig() function (with dot notation) to save the plot to an image file in the current working directory.

Syntax:- plt.savefig('f_name')

This is not strictly necessary in all environments but Sololearn requires it in order to display your graph.

On a side note, you do not even need to import numpy in this code as you are not using an array.
