It really depends on how you structure your code. SymPy expressions are immutable, so if you just assign each step to a different variable, you can easily refer back to previous variables.
You should also be careful with Jupyter notebooks that if you delete cells, or insert cells before other cells, you may end up with a notebook that doesn't actually execute again if you open it again later, because when you start a notebook from scratch the cells are always executed from top to bottom, which may not be the original execution order. It can sometimes be a good idea to "restart and run all" in your notebook to reset the state and ensure everything runs again.
