How do I output data to a CSV file with headers?

问题

I want to output this data to a csv file. Currently, it's not appending anything when getting to the css_selector the text is not being appended. I want to append it to a list, then in a dataframe and then to a csv file.

list1=[]
for i, j in df1.iterrows():
    name = j[1]
    id1 = j[2]
    sleep(3)
    BI_box = WebDriverWait(driver, 
    10).until(EC.presence_of_element_located((By.ID,'BI')))
    BI_box.send_keys(id1)

    Last_Name_box = WebDriverWait(driver, 
    10).until(EC.presence_of_element_located((By.ID,'last')))
    Last_Name_box.send_keys(name)

    Sea= WebDriverWait(driver, 
    10).until(EC.presence_of_element_located((By.ID,'srch')))
    Sea.click()
    try:
        elm_result = driver.find_element_by_css_selector("span.flex[ng- 
        bind='(lbecord.F)']").text
        list1.append(elm_result)
        print(elm_result)
        print(list1)
    except:
        pass
    try:
        elm_result4 = driver.find_element_by_css_selector("span.flex[ng- 
        bind^='(la.record.B_DT ']").text
        list1.append(elm_result4)
    except:
        pass

    try:
        elm_result12 = driver.find_element_by_css_selector("span[ng- 
        bind='row.RISK_IND']").text
        list1.append(elm_result12)
    except:
        pass
    sleep(2)
    clear_btn = driver.find_element_by_id('clr')
    clear_btn.click()
    sleep(2)
    print(list1)

How do I solve the problem?
