'func' should not be creating and returning the list 'm'.  'func' should
return a single value--the value of the integrand.  So you could try
changing line 45 from 'Dl = a*f' to 'return a*f'.  Then your call to romberg
computes d_L, and you will need to compute mu with that value.  If you are
going to generate a graph, you will also need a loop somewhere to compute
the integral for a sequence of values.  Currently you are only computing the
integral with fixed limits (z=0 to z=1.5).

Also, if omega_k is 0.0, then the condition in line 14 will be False, and
lines 16-26 will not be executed.
