Wordclouds are a popular way to visualize the frequency of words in a given text. The larger and bolder the word, the more frequently it appears in the text.
In Python, the wordcloud package simplifies the process of generating wordclouds. In this tutorial, we will discuss how to install and use the wordcloud package in Python.
Step 1: Installing Wordcloud
Before you begin using the wordcloud package, you need to install it first. Installation can be done using the following command:
|
1 |
pip install wordcloud |
Alternatively, if you are using Anaconda, you can install wordcloud using conda:
|
1 |
conda install -c conda-forge wordcloud |
Once the installation is complete, you can import the package into your Python script.
Step 2: Importing Required Libraries
Start by importing the necessary libraries for this tutorial:
|
1 2 |
from wordcloud import WordCloud import matplotlib.pyplot as plt |
Step 3: Creating a Wordcloud with Sample Text
Next, create a sample text to generate a wordcloud from:
|
1 |
sample_text = "wordcloud tutorial python package installation visualization frequency words text size" |
Now, create a WordCloud object and pass the sample text to generate the wordcloud:
|
1 |
wordcloud = WordCloud(width=800, height=800, background_color='white', min_font_size=10).generate(sample_text) |
By supplying values to the parameters, you can customize features such as the width, height, background color, and minimum font size of the wordcloud.
Step 4: Displaying the Wordcloud
Lastly, visualize and display the wordcloud using matplotlib:
|
1 2 3 4 5 |
plt.figure(figsize=(6,6), facecolor=None) plt.imshow(wordcloud) plt.axis("off") plt.tight_layout(pad=0) plt.show() |
This will display an image of the generated wordcloud.

from wordcloud import WordCloud import matplotlib.pyplot as plt sample_text = "wordcloud tutorial python package installation visualization frequency words text size" wordcloud = WordCloud(width=800, height=800, background_color='white', min_font_size=10).generate(sample_text) plt.figure(figsize=(6,6), facecolor=None) plt.imshow(wordcloud) plt.axis("off") plt.tight_layout(pad=0) plt.show() |
Conclusion
In this tutorial, we have learned how to install and use the wordcloud package to visualize the frequency of words in a text. The wordcloud package provides an easy and efficient way to create wordclouds in Python, and its customization options enable you to tweak the appearance to your preference. Experiment with the text and settings to create engaging wordclouds for your next project.
