I have 4+ years of experience in Python and worked in 30+ projects. I also have a lot of experience in debugging existing code and solving the problems.
If your project is already configured in the new environment and I just have to debug it, then it should be done in a single day. However, if you need the project to be configured in a different environment, then it might take more than a day.
All in all, I think I am perfectly capable of meeting your requirements.
