I started using python and ubuntu last year, without any prior knowledge. I started with ROS for school purposes. Without knowing anaconda and ROS has a lot of conflict working together, my python environment is not working properly. For example
which python
gives me a directory that does not exist. And a lot of the packages are not working properly due to the different versions of python it is installed in.
env | grep PATH; env | grep ROS
the command above gives me the following:
ROS_PACKAGE_PATH=/home/sean/turtlebot2i/src:/opt/ros/kinetic/share
LD_LIBRARY_PATH=/home/sean/turtlebot2i/devel/lib:/opt/ros/kinetic/lib:/opt/ros/kinetic/lib/x86_64-linux-gnu

Should I just reinstall python or just ubuntu in general? And is there any suggestions of using python in the future? For example I have read that using apt-get instead of pip is always better.
Thanks for any response in advance.
