Error with append with python csv file

Question

I have a code that sends information to a csv. When it runs the first time it writes the file normally, but when it runs the second time it should add a new line in the file it ends up overwriting the whole file:

        with open('\\offline.csv', 'a', encoding='utf-8', newline='') as f:
        try:
            writer = csv.writer(f)
            writer.writerow((hw_Processador(), hw_Fabricante_PlacaMae(), hw_Modelo_PlacaMae(), hw_NS_PlacaMae(), sis_HostName(), sis_SistemaOperacional(), sis_Data_Instalacao(), sis_Dominio(), sis_Arquitetura(), sis_Usuario_Atual(), rede_IPV4(), rede_MacAddress(), rede_DNS(), hw_Memoria_RAM(), hw_HD(), nome_tecnico, local_mapeamento))
            print('SEM CONEXAO! ARQUIVO CSV GERADO.')
        finally:
            f.close()

Would anyone have any idea what might be going on?

Answer 1

 with open('\\offline.csv', 'a', encoding='utf-8', newline='') as f:

Aim to do this line without the newline:

 with open('\\offline.csv', 'a', encoding='utf-8') as f:
