Matlab is a lot faster than Python. At least an order of magnitude, once you move out of calls to LAPACK et al. It has been improved quite a bit on that front.
So Python is often not a realistic alternative. This is where initiatives like Mojo come in. They will be at least an order of magnitude faster than Matlab again.
But if you want to get people to move from Matlab to a powerful Open-Source alternative: Julia has a syntax that is much closer to Matlab than Python's. I had good success to get colleagues to use Julia which wouldn't look at Python, because the syntax was too far out of their comfort zone.
