  We present pcigale, the port to Python of CIGALE (Code Investigating Galaxy
Emission) a Fortran spectral energy distribution (SED) fitting code developed
at the Laboratoire d'Astrophysique de Marseille. After recalling the specifics
of the SED fitting method, we show the gains in modularity and versatility
offered by Python, as well as the drawbacks compared to the compiled code.
