我尝试使用BeautifulSoup从网页中提取数据并将数据格式化为.csv文件。我已经成功地将数据放入页面中，但我无法正确格式化文件。
我的问题是，如果我在第一列有10个项目（11行标题），下一列的数据从我的第12行开始。.csv最终看起来交错（像楼梯），例如：

Field1,Field2,Field3
data1,,
data1,,
data1,,
,data2,
,data2,
,data2,
,,data3
,,data3
,,data3

字符串
显然，使用.csv格式会更容易：

Field1,Field2,Field3
data1,data2,data3
data1,data2,data3
data1,data2,data3

我的代码看起来像这样：

import time
import requests
import csv
from bs4 import BeautifulSoup

# Time to wait between each item.
t = .010

# Create a csv file to write to.
f = open('filename.csv', 'w')
fieldnames = ('Field1','Field2')
writer = csv.DictWriter(f, fieldnames = fieldnames, lineterminator = '\n')
writer.writeheader()

# Define target page.
url = 'https://www.example.com'
page = requests.get(url)
soup = BeautifulSoup(page.text, 'html.parser')

# Filter useful information from the page.
data_list = soup.find(class_='class0')
data_raw = data_list.find_all(class_='class1')
otherData_raw = otherData_list.find_all(class_='class2')

# Extract [data1] from html.
for data_location in data_raw:
    data_refine = data_location.find_all('a')

    for data_item in data_refine:
        field1 = data_item.contents[0]
        writer.writerow({'Field1':field1})
    time.sleep(t)

# Extract [data2] from html.
for otherData_location in otherData_raw:
    otherData_refine = otherData_location.find_all('a')

    for otherData_item in otherData_refine:
        field2 = otherData_item.contents[0]
        writer.writerow({'Field2':field2})
    time.sleep(t)

f.close()

我已经尝试了一些解决方案，但没有任何运气。我是Python的初学者，所以如果这是一个愚蠢的问题，我提前道歉。我非常感谢任何帮助这个问题。谢谢！
