Importing CSV into MySql workbench table with different columns - mysql

Question

I have several CSV files in one folder with the same structure and would like to import it to a Database for further analysis.
The CSV columns are the following:
Company_Code , Company_Name , Year , Account_number , Account_Description, Value
My intention is to use this CSV to populate 3 tables in my DB in MySQL Workbench. This tables are responsible for organizing:
company_data: id, code and name.
Accounts: id, account number and account description.
Values: companyID, accountID, year and value.
I want to always keep the relationship between company values and account, but in a way that makes easier queries and analysis.
I have tried python but i can't figure out how to attach foreign keys. I don't know if its better to import to a temporary table and then populate each table, directly in MySQL workbench
Edit:
For my python approach i was trying to retrive data from an XML file that has the same information but it started getting to techinical because I would need to implement several valdations that with the CSV are not necessary.
import xml.etree.ElementTree as ET;
import csv
import mysql.connector;
mydb = mysql.connector.connect(
host = "localhost",
user = "root",
passwd = "########",
database = "cvmsanepar"
)
mycursor = mydb.cursor();
mycursor.execute("CREATE TABLE CVM (conta VARCHAR(255), descricao VARCHAR(255), valor1 INTEGER(10), valor2 INTEGER(10), valor3 INTEGER(10))");
dfpTree = ET.parse("InfoFinaDFin.xml");
dfpRoot = dfpTree.getroot();
conta1 = []; #codigo CVM do plano de contas (accounts)
descricao = []; #descrição do plano de conta (account description)
valor1 = []; #valor ano do documento (value year 1)
valor2 = []; #valor ano anterior (value year 2)
valor3 = []; #valor ano anterior do anterior (value year 3)
for numeroDeConta in dfpRoot.iter('NumeroConta'):
conta1.append(numeroDeConta.text);
for descricaoConta in dfpRoot.iter('DescricaoConta1'):
descricao.append(descricaoConta.text);
for valor in dfpRoot.findall('InfoFinaDFin'):
valor1.append(valor.find('ValorConta1').text);
valor2.append(valor.find('ValorConta2').text);
valor3.append(valor.find('ValorConta3').text);
def merge(conta1,descricao,valor1,valor2,valor3):
mergedList = [(conta1[i], descricao[i], valor1[i], valor2[i], valor3[i]) for i in range(0, len(conta1))]
return mergedList
sqlFormula = "INSERT INTO CVM (conta, descricao, valor1, valor2, valor3) VALUES (%s,%s,%s,%s,%s)"
mycursor.executemany(sqlFormula, merge(conta1,descricao,valor1,valor2,valor3));
mydb.commit();
