use dome sort of python format.

First, awesome project. I see it'd be valuable in the future for beginners.
But there are some points that I do not understand.
So I've decided to leave an early issue since it can be hard to fix later in the future.

Summary

• I know it states that you can use blah blah if you use python3
• But considering this is for beginners, everything should be written in Python 3
  • currently, it seems it's based in Python 2
• or at least it should be consistent
  • sometimes it uses the print statement as in Python 2
  • sometimes it uses the print(...) function as in Python 3
  • check this file for example

Suggestion

• Drop Python 2 support or at least use Python3 as a base default language
• Why?
  • Python 2 is (almost) dead (it's legacy now at least)
    • it will only last until 2020
    • it won't get any update but only bug fixes. So, there are no new features
    • it's slow not as optimized as recent Python 3
  • Science community has moved to Python 3
    • Jupyter, for example, has already dropped Python 2....
    • 
  • This is not just science community. The whole community has moved to Python3
    • Django dropped Python2 support
  • Remember Zed Shaw who was the author of Learn Python Hard Way. He was criticized by the community for recommending Python 2 over Python 3 a year ago and now he uses Python 3.

It looks inconsistent that the first code snippet has a print(...), but not the others in Lab01-6.ipynb.

• print(sum(3, 4))
• print(sum(3, 4, 5))

Just copy your image in the comment. Then, it will show upload the image and show the markup like ![image](https://cloud.githubusercontent.com/assets/901975/24061477/eaa17e2a-0b9a-11e7-942d-947b79a9cddd.png)

Then, just copy the text markup in your notebook. Easy. No need to save image as a file.
