Hi @JeffXiePL here are my changes to your update, namely:

• Use primer_design to design the primers based on the CDS sequence. This is the biggest change. The function primer_design allows you to provide a sequence, and a desired Tm, and designs the primers for you. This should be the preferred way of designing primers in pydna.
• A few small typos + variable naming conventions. In python, variables and functions should be written in "snake_case", and without uppercase. More info on what snake_case is and other conventions, see https://www.freecodecamp.org/news/snake-case-vs-camel-case-vs-pascal-case-vs-kebab-case-whats-the-difference/

By the way, very cool using min and max on a SeqFeature to get its edges. I did not know this was possible and it's very convenient!

Thanks again for your contribution!
