bellman_ford is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version and a Python version.
dijkstra, a Python code which implements a simple version of Dijkstra's minimum distance algorithm for graphs.
toms097, a Python code which computes the distance between all pairs of nodes in a directed graph with weighted edges, using Floyd's algorithm.
