The resulting graph must be as follows:

This bar graph is called a scree plot.

Hint: To create the list PCs for the x-axis labels, you can either define as

PCs = ['PC1', 'PC2', 'PC3', 'PC4', 'PC5', 'PC6', 'PC7', 'PC8', 'PC9', 'PC10', 'PC11']

A smarter way to do this is to use a shorthand for loop as follows:

PCs = [f'PC{i+1}' for i in range(n)]

Hint: Replace the ????? part with your solution.

fig = plt.figure() ax = fig.add_axes([0,0,1,1]) PCs = [f'PC{?????}' for i in ?????] ax.bar(?????,?????) plt.show()
