Pandas dataframe to CSV can do this easily,

Step1: Start with an empty dataframe and fill it while you loop

pypd_df1 = pd.DataFrame(data, columns=["Product_Url","Product_Manufacturer","Product_Model","Product_color","Product_memory","Product_Price","Currency","VAT","Shipping Cost","Country","Date"])

Step2: Add rows to existing dataframe or consider this while you deal with dataframes in python.

pypd_df1.loc[len(pypd_df1)] = [Product_Url_var_name, Product_Manufacturer_var_name, ...]

You may find Python's writelines method interesting sometimes.
