flask !# use/bin/env python2/3

I am a bit worried about one of the tutorial videos that I watched where Kenneth put the following at the top of a script "!# use/bin/env python2/3" and said that all mac users should do this for the script to run... I am a mac user but do not like python 3....... Do I have to program in python 3 in order to use and deploy flask websites?

No, you do not need python 3 to use and deploy flask. However, to follow along with the tutorial and complete the coding challenges you will have adapt your knowledge of python 2 to python 3 (at least, as far as I can tell, these tutorials and such are in python 3). Python 2 and 3 are quite similar on the most basic level; however there are some important differences and you will inevitably run into trouble trying to work through a python 3 tutorial coding in python 2 unless you get very familiar with the differences in syntax and functionality. Here is a great starting point: http://sebastianraschka.com/Articles/2014_python_2_3_key_diff.html
