To output a new CSV file, we can use the .to_csv method with a name for the file in quotation marks. For example, since we added the percent_total column to the refugee_df DataFrame, we may want to download the updated DataFrame as a CSV file to use it with other programs.
refugee_df.to_csv("new_refugee.csv", encoding='utf-8', index=False)In addition to a filename, we’re also specifying that the encoding is utf-8 and that the Index (the bolded left-most column) is not included in the CSV file.
