when I run python code by python interpreter on zeppelin, is it run on spark engine or not

[#1]

I need to run python code on zeppelin with spark engine and adding python interpreter on zeppelin then run python code but, I dont know, is python code run by spark engine? or not?

if not, how can run python code by spark engine on zeppelin?

[#2]

it is not run in Spark, it will be run directly in Python. You'll need the interpreter %spark or %spark.pyspark Interpreter instead

[#3]

I have python and java codes. is there any way to convert python or java codes to pyspark or spark?

[#4]

with pyspark you can execute python code, you might have to check the library pathes. When you use Java, you can use the Spark API 'native', but i don't know if this can be done in Zeppelin.
