Cython (included with Sage) converts Python-like code into C which can then be compiled into a shared-object library and used by Python / Sage. It's intended use is to write code that is easy to use like Python but is optimized to use fast C data types instead of slower Python data structures. However, one could certainly just write Python without any optimizations and have Cython generate the C equivalent.

Create a .pyx file containing your code and execute

$sage -cython -a mycythonfile.pyx  This will output a corresponding .c file which can be compiled into a shared object library and imported in Python along with an.html file that neatly shows the C equivalent of each line of code.

This will output a corresponding .c file which can be compiled into a shared object library and imported in Python along with an.html file that neatly shows the C equivalent of each line of code.

Be warned that the corresponding C code, though optimized, looks really messy.
