Frequently Asked Questions
These are the answers to our most common questions. If you have a question that's not answered here, please contact us.
What is trinket?
trinket is an all-in-one coding environment designed for education. Teachers and students use trinket to code during class, while online courses and coding clubs use trinket to make interactive projects for their students.
How can I get started with trinket?
Try out some of our sample projects! There are examples on your "My Trinkets" page. We also have some video projects on our blog you might enjoy.
If you're looking for basic Python knowledge, take a look at our website hourofpython.com. Or, if you're looking for more general information about using this site, head over to docs.trinket.io.
Are there any example trinkets that I can look at?
Yes! We feature trinkets on our Twitter account. Click here to see the latest featured trinkets.
How do I get in touch with a real person?
That's easy! Just contact us.
We respond to most questions within one weekday. We are based in the US, so expect a slightly longer response time if you're located in another time zone. We occasionally send out automated responses to common questions, but we read every user message.
How can I help?
Share feedback about your experience using trinket as a teacher or student! Your feedback and suggestions tell us what we're doing well and what we need to work on.
If you're a developer, you can help by getting involved with the open source projects we use. Take a look at github.com/trinketapp to find out what we're working on now. If nothing there catches your eye, get in touch.
What languages do you support?
trinket supports Python, Blocks, HTML5, and GlowScript.
What version of Python do you use?
We believe that Python 3 is the future of the language, yet Python 2 materials are still very common, so supporting both seamlessly is ideal for an educational code editor. We provide both a free Python trinket that supports a large subset of both versions and a premium server-side Python 3-only trinket. Our free Python trinket supports both Python 2 and 3 syntax seamlessly, allowing beginners to use code from either version of the language successfully. The free Python trinket defaults to Python 3 syntax where the versions are incompatible, such as the division operator. Our premium Python 3 Trinket is for those who need the full power of Python 3, with strict syntax interpretation.
There's more! You can force strict evaluation of either Python 2 or Python 3 syntax in our free Python Trinket. To require Python 2 style syntax, add the comment
#!/bin/python2as the first line of your trinket. To require Python 3 style syntax, add the comment
#!/bin/python3as the first line of your trinket. These 'shebangs' are based on the convention for specifying script interpreters in UNIX-like systems.
How is the Blocks trinket different from Scratch?
The Blocks trinket is intended to be a bridge into Python for students who have experience programming with Scratch. Students move and snap blocks together as in Scratch, but the blocks have commands that are more like Python's commands. After putting a program together, students can view the Python code and make connections between the familiar block shapes and the code.
