Python Data Set
###########

The Python/R dataset enables users to create a dataset by writing a Python or R script that directly retrieves data.
The developer of the dataset is free to write code which has to produce a **dataframe** variable as output (for Python scripts we refer to pandas dataframes). This variable will contain data that Knowage will later convert into its own format.

As shown in the picture in the field **Dataframe variable name** the developer has to specify the name of the variable in which the final output of the script is stored in the form of a dataframe.

In the field **Python environment** the user can select a working environment among the available ones defined in the **Configuration Management** section.

Inside the scripts it is possible to use parameters by the usual syntax *$P{}*.
