Python Tutor helps people overcome a fundamental barrier to learning programming: understanding what happens as the computer executes each line of a program's source code. Using this tool, you can write Python, Java, JavaScript, TypeScript, Ruby, C, and C++ programs in your Web browser and visualize what the computer is doing step-by-step as it executes those programs.
This repository makes some small modifications to the original code to provide it as a Docker service to embed the interface on UNCode and allow users to visualize their code in Python3, C/C++ and Java.
The container is deployed in Docker Hub: unjudge/onlinepythontutor.
The official website of the project is: http://pythontutor.com/.
This tool was created by Philip Guo in January 2010. See project history.
To view all documentation related to this project check the docs. For additional documentation, please refer to the Wiki.
As this repository in only focused on supporting this utility for UNCode, there are two options to deploy and embed this on UNCode. This integration is also done in the organization main repository, in the multilang plugin.
Check the iframe embedding documentation for a better understanding on how this works.
However, it can be hard to run your own visualizer locally for non-Python languages, since it is necessary to deploy
a service called cokapi, check the documentation. This service also needs a backend to run
C/C++ code, this is located in the repository opt-cpp-backend.
To understand more how to deploy this service, check this script, which automatically deploys it when UNCode is deployed automatically.
For further directions, see Overview for Developers or explore the rest of the docs.
To run the container, you can either pull it from docker hub:
docker pull unjudge/onlinepythontutorOr build it:
docker build -t unjudge/onlinepythontutor ./
docker run -p 8003:8003 -e PY_CMD=python3 unjudge/onlinepythontutor To visualize python 2.7 code, run the container using the environment variable PY_CMD with python, rather than python3.
You should see the visualizer at: http://localhost:8003/visualize.html
If you want to run locally on your own computer, to run Python visualizations try:
pip install bottle # make sure the bottle webserver (http://bottlepy.org/) is installed
cd OnlinePythonTutor/v3/
python bottle_server.py
You should see the visualizer at: http://localhost:8003/visualize.html and the live programming environment at: http://localhost:8003/live.html
