Question

我使用BeautifulSoup来解析数据，现在我想将它保存到csv文件中。我能够创建一个csv文件;但是，当我打开文件时，它是空白的。我应该写什么来写一个csv文件？

脚本：

university = {}

for x in soup.find_all('p'):
    name_tag = x.find('strong')
    if name_tag != None:
    name = name_tag.text
    t = x.text
    m = re.findall('\$([0-9]*)', t)
    if m != []:
        print(name +', ' + m[0])

部分输出：

Harvard University:, 400
Stanford University:, 400
Stanford University:, 400

写入csv文件：

import csv

with open ('gifts.csv', 'w', encoding="utf-8") as file:
    writer=csv.writer(file)
    for row in university:
        writer.writerow(row)

您没有向变量university添加任何内容，请将代码更改为：

import csv
university = []

for x in soup.find_all('p'):
    name_tag = x.find('strong')
    if name_tag != None:
        name = name_tag.text
        t = x.text
        m = re.findall('\$([0-9]*)', t)
        if m != []:
            university.append([name +', ' + str(m[0]]) # append to variable university

with open('gifts.csv', 'w') as f:
    writer = csv.writer(f)
    for row in university:
        writer.writerow(row)
