Word clouds are one of the most common methods of representing the textual dataset in a graphical format. A word cloud can also be used for sentiment analysis by analyzing text. In this article, I’ll walk you through a tutorial on word cloud with Python.
What is a Word Cloud?
A word cloud is more than a simple graphical representation of textual data. In data science, it plays a major role in analyzing data from different types of applications. A word cloud is a graphical representation of words, i.e. tags, which are used to represent the frequency of entities in a particular data set.
In Data Science, word clouds are mainly used to visualize the most frequent words in a graphical representation to identify keywords of different sizes and colours based on the frequency of the words.

In general, the text represented by word clouds is visualized in such a way that the most frequent words in a particular piece of text appear larger than the less frequent words.
Word Cloud with Python Tutorial:
Hope you now know what word clouds are and why they are used in data analysis. In this section, I’ll walk you through a tutorial on creating a word cloud with Python.
To create a word cloud with the Python programming language, I’ll be using Google Play Store Reviews data which can be easily downloaded below. Now let’s import the necessary Python dataset and libraries and start building a word cloud with Python:

| 4 | 5 | This app is very good as everyone knows. Here … |
The above data is only for 5-star ratings in Google Play Store reviews, now I’m going to import data from 1-star reviews to make the word cloud interesting:
df2 = pd.read_csv('one_star_reviews.csv')
df2.head()| Rating | Review | |

Final Step:
Now let’s see how to create a word cloud with Python by using the WorldCloud and Matplotlib libraries in Python:
So this is how we can generate word clouds with Python for analyzing textual data. I hope you liked this article on word cloud tutorial with Python. Feel free to ask your valuable questions in the comments section below.
