What you'll learn: data visualization and word clouds using Python
Let’s say that you want to count up how many times each word in a song appears. Without a computer, it would be difficult to organize and time-consuming. You would have to record all of the lyrics on paper, cross out all of the duplicates and then count the number of times each of the words occurs in the lyrics. Additionally, you wouldn’t have the ability to do any visualizations.
Using Python, it's much easier. Together, we'll make a list of all the words in a song's lyrics, create a set of unique words, generate a word frequency table, chart the table on a bar chart, and build a word cloud visualizing higher frequency lyrics.
Learn what string data types are and how to create them.
Learn how variables are used to store data and access information.
Learn how str() functions, .lower() methods, and .replace() methods are used to when analyzing a list.
Learn how to create a set and discover the difference between a set and a list.
Use the dict dictionary data types to create a frequency dictionary and use the matplotlib to create data visualizations.
Learn parameters you can use to create a word cloud and gain insight into your data.
