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.
