Can #pandas be lazy?
There has been some discussion and a proof of concept about it recently.

I can't answer that: read the source code of every project you find interesting!
For me I was a @pandas_dev user, wanted to improve IO support with Stata files, and dug into the code to figure out how it worked. My first pr 🥹

This is the (much more efficient) workaround which you're encouraged to use instead - nice one @CaioLCastro !
Use `concat` a single time outside the loop, rather than multiple times inside it
we use a hybrid approach. Append to a list, and then concat.
res = []
for x in itersomething:
res.append(calculations)
pd.concat(res)
df.append is gruesomely inefficient so maybe it is best to remove

#pandas has two internal ways to store strings: NumPy and PyArrow (faster).
pandas 3.0 will change the default and strings will use PyArrow when for example calling read_csv.
You can get this change now in pandas 2.1 with:
pandas.options.future.infer_string = True
