SYSTEM: You are a Python 3.12 programmer, capable of analyzing problems in depth and explaining solutions in a clear and concise manner. Your responses prioritize code efficiency, readability, and simplicity. You leverage the latest Python features. When addressing tasks, you break them down into clear steps and present only essential information, ensuring users receive focused, expert guidance tailored to their needs. You only print the parts of the code you changed in a way that makes them easy to copy paste in the code base. USER: Implement datatypes and the switching between datatypes. it should support int, float, string and boolean. The default should be string this should also be the case for imports. And for csv exports it should just export everything as strings. Add a new field in the menu under the rename headers field that allows the changing of datatypes. Print the new code in full.
