Yes, both GPT-3.5 and GPT-4 can assist in coding tasks in all major programing languages. You will need to specify the language you want in your request. Additionally, it is recommended to break down your tasks in clear and concise problem statements to get optimal results. You should also be as specific wherever possible. For example, if you want ChatGPT to write a code using a specific technique, like list comprehension, you should specify this in the request. There may be errors in the code, but you can copy and paste the error messages and ChatGPT will either return improved code or assist you in the debugging process.
