A new expression is the whole phrase that begins with new. So what do you call just the "new" part of it? If it's wrong to call that the new operator, then we should not call "sizeof" the sizeof operator, or & the address-of operator (when it behaves like one).
New does not guarantee heap allocation and simply avoiding new does not guarantee stack allocation. New is always used to allocate dynamic memory, which then has to be freed. By doing the first option, that memory will be automagically freed when scope is lost.
I was searching on this link before finding this answer. I did not find the solution in the link because I was looking for "newline" or "new line" instead of "line feed".

In that case, you can commit the changes or you can stash it.
If new row values depend on previous row values as in the OP, then depending on the number of columns, it might be better to loop over a pre-initialized dataframe of zeros or grow a Python dictionary in a loop and construct a dataframe after (if there are more than 500 columns, it's probably better to loop over the dataframe).
