Yeah they do. Python is a godsend for small quick iterative development, but it doesn't scale well to a team of hundreds of people with a bajillion lines of code. Testing in Python is very nice (in part due to its dynamic nature, the thing that can cause bugs in larger systems) so if you have proper coverage and a good test suite (which everyone does... Right? :P) its not too bad. Type hints are also definitely going to help this.
