You can leverage [Zeppelin Dynamic Form]({{BASE_PATH}}/manual/dynamicform.html) inside your Python code.

## Zeppelin features not fully supported by the Python Interpreter
* Interrupt a paragraph execution (`cancel()` method) is currently only supported in Linux and MacOs. If interpreter runs in another operating system (for instance MS Windows) , interrupt a paragraph will close the whole interpreter. A JIRA ticket ([ZEPPELIN-893](https://issues.apache.org/jira/browse/ZEPPELIN-893)) is opened to implement this feature in a next release of the interpreter.

## Pandas integration
[Zeppelin Display System]({{BASE_PATH}}/displaysystem/basicdisplaysystem.html#table) provides simple API to visualize data in Pandas DataFrames, same as in Matplotlib.
Example:
```python
import pandas as pd
rates = pd.read_csv("bank.csv", sep=";")
z.show(rates)
```
