使用python可以在csv中修改和添加新行吗？

import csv

with open('data.csv', 'w', newline='') as file:
    # 在这里进行后续操作
    ...

writer = csv.writer(file)

# 修改行
row = ['John', 'Doe', 'john@example.com']
writer.writerow(row)

# 添加新行
new_row = ['Jane', 'Smith', 'jane@example.com']
writer.writerow(new_row)

file.close()

import csv

# 打开CSV文件
with open('data.csv', 'w', newline='') as file:
    # 创建CSV写入器
    writer = csv.writer(file)

    # 修改行
    row = ['John', 'Doe', 'john@example.com']
    writer.writerow(row)

    # 添加新行
    new_row = ['Jane', 'Smith', 'jane@example.com']
    writer.writerow(new_row)

# 关闭CSV文件
file.close()
