--------------------------------------------

             Summary: Dynamic forms in Python interpreter do not work 
                 Key: ZEPPELIN-1655
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-1655
             Project: Zeppelin
          Issue Type: Bug
          Components: python-interpreter
    Affects Versions: 0.7.0
            Reporter: Alexander Bezzubov
             Fix For: 0.7.0


ZEPPELIN-1345 updates  [Python `PyZeppelinContext` | https://github.com/apache/zeppelin/blob/master/python/src/main/resources/bootstrap.py#L121] and [Pyspark `PyZeppelinContext ` |https://github.com/apache/zeppelin/blob/master/spark/src/main/resources/python/zeppelin_pyspark.py#L53] but does not touch [Python `Py4jZeppelinContext`|https://github.com/apache/zeppelin/blob/master/python/src/main/resources/bootstrap_input.py#L28] - wich is used for dynamic forms, in case `py4j` is installed on the system for things like

```
z.select("Choose a letter", 
    ([a,"a"], [b,"b"], [c,"c"]
```

In latter case Python interpreter becomes not useable - any line results in

```
x = 1

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'Py4jZeppelinContext' object has no attribute '_displayhook'
```
