#### In a Python Notebook **Note**: In the following examples we are using the Spark master URL `spark://master:7077` that shall be replaced by the URL of the Spark master.
#### In Python
The **same Python version** need to be used on the notebook (where the driver is located) and on the Spark workers.
The python version used at driver and worker side can be adjusted by setting the environment variables `PYSPARK_PYTHON` and / or `PYSPARK_DRIVER_PYTHON`, see [Spark Configuration][spark-conf] for more information.
```python ```python
import os from pyspark.sql import SparkSession
# make sure pyspark tells workers to use python3 not 2 if both are installed
os.environ['PYSPARK_PYTHON'] = '/usr/bin/python3' # Spark session & context
spark = SparkSession.builder.master('spark://master:7077').getOrCreate()
