While dealing with pandas DataFrames, we save these DataFrames in the form of the CSV file, sometimes we need to make changes to these existing CSV files.Problem statementGiven a Pandas DataFrame, we have to add it to an existing CSV file....

DataFrame.append() ought to have a "inplace=True" parameter to allow modifying the existing dataframe rather than copying it. This would be a big performance gain for large dataframes.
