Adding a legend
A legend can be useful when plotting multiple datasets to identify which plot is associated with a specific dataset. To add a legend, you can use the label argument. To display the legend on the plot, you can use the function plt.legend().
matplotlib.pyplot is imported as plt and lists stock_A and stock_B are available in your workspace.
