For those who u might ask why the dnaRepalce is outside of the function body.
The reason is it don't need to be build everytime the func is called, so this solution is faster than those who put the replacer inside of the func body.

wouldn't work on non ASCII characters

No one is faster: https://stackoverflow.com/questions/26540885/lambda-is-slower-than-function-call-in-python-why

lambda is indeed faster, but according to the PEP8, it is preferable to use the def statement

i like it picasso

this is a cosmic level python solution

lol

i think lambda is faster than def, maybe not sure tho

It seems to me that all previous years were better, since the point is not in readability, but in the beauty of the code)

you can use pythontutor.com to see it in action

how did you know you should loop it?

I love this, how did i not think about this.
well done and thanks
