Interpreters are a concept that Zepl has taken in from Apache Zeppelin. Interpreters enable users to use a specific language/data-processing-backend from the notebook. Groups of these data processing backends, packaged with critical libraries for analytics, are available to select from the notebook as an image. For example, to use Python code in Zepl notebooks, you write code using the%python
interpreter, which points to an image which contains a Python environment with customized libraries.
