[Tutor] A couple newbie questions about Python

[Deb Wyatt]

Hi.  Everywhere I have read, the 'standard practice' for indentation is 4 spaces, but I am running into 2 space indentation in a lot of tutorials and such.  Should I keep with the 4 spaces, or does it even matter, as long as it is consistent?

I just recently became aware of the inaccuracy of calculations using floats and I am concerned about that.  

I am using Python 3, just fyi.

Thanks for any enlightenment on these questions.
