Getting pyspark working

Hi there.
I couldn't find any documentation for initializing pyspark.

I've initialized the spark sessions with

```
%%classpath add mvn
org.apache.spark spark-sql_2.11 2.3.1
````
followed by
```
%%spark
```

Everything is all good.

Then when I go to link the spark session in python I don't have an entry point to the spark because spark has been initialized through the jar files and not through python.

Is there a tutorial or documentation which outlines how to use spark in python or through pyspark?

Cheers.
