How do you plot a figure in Python?

Following steps were followed:

Define the x-axis and corresponding y-axis values as lists.
Plot them on canvas using . plot() function.
Give a name to x-axis and y-axis using . xlabel() and . ylabel() functions.
Give a title to your plot using . title() function.
Finally, to view your plot, we use . show() function.
