Plot a bar using matplotlib using a dictionary

First, we can define our dictionary and then, convert that dictionary into keys and values. Finally, we can use the data to plot a bar chart.

Steps

• Create a dictionary, i.e., data, where milk and water are the keys.

• Get the list of keys of the dictionary.

• Get the list of values of the dictionary.

• Plot the bar using plt.bar().

• Using plt.show(), show the figure.
