10. Cython: basic language constructions (part 2)

1. Questions?
2. Upcoming topics:
   • Numpy -- numerical n-d arrays of data
   • Databases: SQLite (and SQLalchemy), Mongodb (a noSQL database).
   • Sage development: debugging, profiling, modifying the sage library, using trac
   • Interfaces: using Octave, Matlab, Mathematica, Maple, R, etc., from Sage.
   • Elementary number theory: primes, prime factorization, integers modulo n, continued fractions, elliptic curves
   • Statistics: using R in Sage, quantitative finance
   • Calculus: symbolic expressions, Taylor series, numerical and symbolic integration
3. Lecture: Today, we will continue from where we left off last time with Cython. Ask questions.
