Class Def Python Try / Except

I'm looking for someone to help me with funciones and clases python. I had always worked with functions but never with functions within functions. When I wanted to run the program I did not perform any of my functions until I changed the def for class as you can see in the code. I'm looking to change this so that I can send the parameters in the def main directly that I want my variables to take within the functions. To be more clear I leave the code as I would like it to be. I need it to be this way since I work with databases that come from another file and I already have everything assembled my database from which I get the parameters from def mail()

Greetings

I need it to be something like this, where I work all the data in my data base in the run ():

def run(d):
    NewTag("url")
    Device = str(d.get("Li_platform")) #Mobile Web 
    Inicio_Li_Platform = ('//*[@id="platform_listbox"]/li[')
    Final_Li_Platform = (']')
    Platform(Inicio_Li_Platform+""+Device+""+Final_Li_Platform)
    NameTag(d.get("TagName"))
    Floor_Rate(d.get("Floor_price"))
    Save_Tag('save')
    Inicio_Li_Publisher = ('//*[@id="publisher_listbox"]/li[')
    Final_Li_Publisher = (']')
    Publisher = str(d.get("Li_Publisher")) #Publisher Altitude
    Publisher_Li(Inicio_Li_Publisher+""+Publisher+""+Final_Li_Publisher)
    Tag_Rate_and_Save(d.get("Tag_Rate"))
    time.sleep(2)


def main():
    login("martin", "pass")
    tags = (nametags)

    for tag in (tag.strip() for tag in tags.split(",")):
        d = (Inventory_data.get("Inventario_datos")).get(tag, None)
        if d:
            run(d)
        else:
            print('Error: Clave "{}" no encontrada.'.format(tag))
    driver.close()


def login(email, passwd):
        url = "url/login/"
        email_find = '//*[@id="form_username"]'
        passwd_find = '//*[@id="form_password"]'
        boton_find = '//*[@id="login_submit"]'
        driver.get(url)
        user = driver.find_element_by_xpath(email_find)
        user.send_keys(email)
        password = driver.find_element_by_xpath(passwd_find)
        password.send_keys(passwd)
        boton_find = driver.find_element_by_xpath(boton_find).click()
