Help With While Loop and Append

[perfringo]

I didn't understand why you wrote 'In' and 'Out' at every alternate line. I had to delete the code in python for it to work.

Sorry about that. This is not 'me', it's ipython who does it on my behalf .

I use interactive interpreter in terminal for one-liners/short code examples and if I copy from there it is how ipython displays it. If you are interested you can have a look at Project Jupyter which provides notebook functionality on top of ipython.

I don't expect oneliners to be copied. I strongly recommend that you enter them yourself. There are several reasons for that: getting comfortable with writing code, muscle memory, you have possibility to understand/learn keywords, functions, methods etc. Nowadays, to be 'computer literate' you must be able to type at least 200 strokes per minute so for one-liners it is much faster to type instead of copying.
