Welcome folks today in this post we will be building a hangman word puzzle game in python using pygame library. All the full source code of the application is given below.

Get Started

In order to get started you need to install the following library using the pip command as shown below

pip install pygame

After installing this library make an app.py file and copy paste the following code

app.py
