如何在创建.csv文件时不跳过Excel中的空单元格

import csv

# 创建.csv文件并写入数据
with open('data.csv', 'w', newline='') as file:
    writer = csv.writer(file, delimiter=',')
    writer.writerow(['Name', 'Age', 'Email'])
    writer.writerow(['John', '', 'john@example.com'])
    writer.writerow(['Alice', '25', 'alice@example.com'])

import pandas as pd

# 创建DataFrame对象
data = {'Name': ['John', 'Alice'],
        'Age': ['', '25'],
        'Email': ['john@example.com', 'alice@example.com']}
df = pd.DataFrame(data)

# 导出为.csv文件
df.to_csv('data.csv', index=False)
