如何从csv文件中删除一行？

import csv

def delete_row(csv_file, condition):
    # 读取csv文件
    with open(csv_file, 'r') as file:
        reader = csv.reader(file)
        rows = list(reader)

    # 定位要删除的行
    delete_index = None
    for i, row in enumerate(rows):
        if condition(row):
            delete_index = i
            break

    # 删除行
    if delete_index is not None:
        del rows[delete_index]

    # 保存修改后的数据
    with open(csv_file, 'w', newline='') as file:
        writer = csv.writer(file)
        writer.writerows(rows)

# 示例：删除第一列值为'John'的行
delete_row('data.csv', lambda row: row[0] == 'John')
