Mari membuat word cloud di Python!

import matplotlib.pyplot as plt

two_cities = "It was the best of times, it was the worst of times, 
        it was the age of wisdom, it was the age of foolishness, 
        it was the epoch of belief, it was the epoch of incredulity, 
        it was the season of Light, it was the season of Darkness, 
        it was the spring of hope, it was the winter of despair, 
        we had everything before us, we had nothing before us, 
        we were all going direct to Heaven, we were all going
        direct the other way – in short, the period was so far
        like the present period, that some of its noisiest
        authorities insisted on its being received, for good
        or for evil, in the superlative degree of comparison only."
