It gives you a lot of freedom and doesn't force many rules like other non-dynamic languages do. This makes it great for trying out ideas and working with data and machine learning. However, when you're writing more complex programs, you need to be more careful. That's why I feel like I encounter more bugs during runtime compared to other languages. I mentioned Go because it makes you stick to a smaller number of ways to do things, which feels more "pythonic".

Hard to tell but that sounds a bit like a test problem. If you have high test coverage (which you must do in a language like python) most bugs should only result through complex interaction.
