One obvious reason is Python's extreme readability, it has often been described as being as close to executable pseudo-code as one can get.
If you're using an LLM to write code I think the rules would be
1. Use a language you know really well so you can read it easily, and add to it as needed.
2. Use a language that has a large training set so the LLM can be most efficient.
3. Use a language that is easy to read.
If your language has a small training set or you don't intend to do much addition or you don't really know any language that well or are restricted from using choice 1 for some reason, 2 and 3 move up, and python has a large training set and it is easy to read.
