CodeSkulptor3 Review

By November 2, 2023February 5th, 2024No Comments

CodeSkulptor is a web-based Python development environment developed by Scott Rixner.  Marie Chatfield designed and implemented an initial version of the current user interface. CodeSkulptor3’s documentation was developed by John GreinerJoe Warren, and Scott Rixner.

We’ve reviewed CodeSkulptor3 for usability, cost, and other classroom-friendly characteristics. CodeSkulptor is a wonderful sketchpad for developing Python, particularly Python games, as there is good flexibility to learn about user input (text, keyboard, and mouse) as well as principles of collision detection, without the need to install any software on the computer.

  • Easy to use and learn, with familiar controls (stop, play, save)
  • Friendly for beginners, but has enough advanced capabilities to make small games
  • saving is a manual process that involves either downloading files, or copying and pasting the URL. If this isn’t done carefully, students may lose work
