A word cloud is an image made of words that together resemble a cloudy shape. The size of a word shows how important it is e.g. how often it appears in a text — its frequency.
Here is a basic python script to create such a word cloud, I have used my favorite classic novel "Pride and Prejudice" by Jane Austen. You can find other such texts at https://www.gutenberg.org/
This is the final project in the "Google IT Automation with Python Professional Certificate"'s course "Crash Course on Python", available on Coursera.
