How to specify Python version to use with Pyspark in Jupyter?

[#1]

Hello, I've installed Jupyter through Anaconda and I've pointed Spark to it correctly by setting the following environment variables in my bashrc file :

export PYSPARK_PYTHON=/home/ambari/anaconda3/bin/python
export PYSPARK_DRIVER_PYTHON=jupyter
export PYSPARK_DRIVER_PYTHON_OPTS='notebook --no-browser --ip 0.0.0.0 --port 9999'.

When i tap $python --version, i got Python 3.5.2 :: Anaconda 4.2.0 (64-bit).

When i tap $which python, i got ~/anaconda3/bin/python.

So, i conclude that I'm using python 3 when i run PySpark in Jupyter. But, i got the error message shown in "result.png" when i used simple instruction in jupyter. So, there's a conflict in python version even if i updated

PYSPARK_PYTHON to /home/ambari/anaconda3/bin/python3 instead of /home/ambari/anaconda3/bin/python and refreshed my bashrc file.
so, how can i fix this issue and use Python 3?

Based on your result.png, you are actually using python 3 in jupyter, you need the parentheses after print in python 3 (and not in python 2). To make sure, you should run this in your notebook:

import sys
print(sys.version)

Thank you so much. I was really confused about which version of Python that requires parentheses after print. I thought it was Python2.
