如何统计csv.writer写的行数？

import csv

# 假设要写入的数据列表为data_list
data_list = [['John', 'Doe', 'john@example.com'],
             ['Jane', 'Smith', 'jane@example.com'],
             ['Bob', 'Johnson', 'bob@example.com']]

# 打开文件并创建csv.writer对象
with open('data.csv', 'w', newline='') as file:
    writer = csv.writer(file)

    # 写入数据并统计行数
    count = 0
    for data in data_list:
        writer.writerow(data)
        count += 1

# 输出写入的行数
print("写入的行数为:", count)
