etc. (depending on the contents of your df) you could try calling the
to_json() function, then writing the resulting JSON string to your
file. Alternatively, you could pickle the dataframe using to_pickle(),
and write that to a file.
|Write-back vs Write-Through|
The benefit of write-through to main memory is that it simplifies the
design of the computer system. With write-through, the main memory
always has an up-to-date copy of the line. So when a read is done,
main memory can always reply with the requested data.
If write-back is used, sometimes the up-to-date data is in a processor
cache, and sometimes it is in main memory. If the data is in a proc

hard list rather than an enumerable that is executed every time you
var bname = buildings.SelectMany(b => b.BuildingName).ToList();
