Good alternative to Pandas .append() method, now that it is being deprecated?

  1. How to solve Good alternative to Pandas .append() method, now that it is being deprecated?

    Create a list with your dictionaries, if they are needed, and then create a new dataframe with df = pd.DataFrame.from_records(your_list). List's “append” method are very efficient and won't be ever deprecated. Dataframes on the other hand, frequently have to be recreated and all data copied over on appends, due to their design – that is why they deprecated the method

I also like the append method.
But you can do it in one line with a list of dicts

df = pd.concat([df, pd.DataFrame.from_records([{ 'a': 1, 'b': 2 }])])

or using loc and tuples for values on DataFrames with incremenal ascending indexes

df.loc[len(df), ['a','b']] = 1, 2

or maybe

df.loc[len(df), df.columns] = 3, 4

This have already good answare, but I just wanted to append something at the end here as I didnt find it 🙂
If you are appending a DF to a DF and want to use concat this is the way I found:

original with append

   outputxlsx = outputxlsx.append( df, ignore_index=True)

concat

   outputxlsx = pd.concat([outputxlsx, pd.DataFrame.from_records(df)])
