Excel is superior to Python in so many ways for many use cases. It is visual (and this already kills the competition. Forget leading three executive through the final m&a python model), you can build small models in seconds or minutes, the learning curve is flatter and hence it reaches more people, auditing is much easier, tiny tweaks can be made much quicker (especially for people who did not setup the model) and it does not require years of studying coding.. i put our interns infront of excel and within 2-3 weeks of hard work they can do their calculations. Impossible for regular business and finance guys if they would have to so this all in python.
