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

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.
@quant_arb 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.

Artificial intelligence may not be so intelligent if it uses pandas .apply() when not strictly necessary. Our operations are usually vectorized (very fast), .apply() is usually not, so it may be very slow. Avoid loops and apply if a pandas operation exists for what you need.
I love GPT-4 code assistant but it uses .apply() for every bit of pandas code and I ain't about it.
