inspect.getsource ignore comments at the end of the function:

for example this function:

def matmul_single(A, x, out):
  from numpy import matmul
  out[:] = matmul(A, x)
  # Some comment here...

using the inspect library:
>>> inspect.getsource(matmul_single)                                                                                                                                     
>>> "def omp_matmul_single(A, x, out):\n  from numpy import matmul\n out[:] = matmul(A, x)\n"

the result does not contain the comments at the end of the function.
