Hi, I want to know what is the best way to keep the databases I use in different projects? I use a lot of CSVs that I need to prepare every time I’m working with them (I just copy paste the code from other projects) but would like to make some module that I can import and it have all the processes of the databases for example for this database I usually do columns = [(configuration of, my columns)], names = [names], dates = [list of columns dates], dtypes ={column: type},

then database_1 = pd.read_fwf(**kwargs), database_2 = pd.read_fwf(**kwargs), database_3 = pd.read_fwf(**kwargs)…

Then database = pd.concat([database_1…])

But I would like to have a module that I could import and have all my databases and configuration of ETL in it so I could just do something like ‘database = my_module.dabase’ to import the database, without all that process everytime.

Thanks for any help.

    I’m not the biggest expert, but wouldn’t this be the whole point of polars’s lazy construction?

      Never heard of that, just saw a video and even if isn’t exactly what I need it’s looked really cool.
