How Fast can Python Parse 1 Billion Rows of Data?

Covered about “One Billion Row Challenge” a couple of times in the newsletter. This is another one by Doug Mercer. He adapted one of the top Python submissions which uses only built-in libraries and he also used a few awesome libraries (polars, DuckDB) that shared that approach too. Of Course, they are not near to the winner approaches for top submissions but using Python libraries we can write simple and elegant solutions which will do the magic in sub-10 seconds.
