如何在python中存储csv中的行值？

import csv

with open('file.csv', 'r') as file:
    # 执行读取或写入操作

with open('file.csv', 'r') as file:
    csv_reader = csv.reader(file)
    for row in csv_reader:
        # 处理每一行的数据

with open('file.csv', 'w', newline='') as file:
    csv_writer = csv.writer(file)
    csv_writer.writerow(['Value 1', 'Value 2', 'Value 3'])

import csv

# 读取CSV文件的行值
with open('file.csv', 'r') as file:
    csv_reader = csv.reader(file)
    for row in csv_reader:
        # 处理每一行的数据

# 写入CSV文件的行值
with open('file.csv', 'w', newline='') as file:
    csv_writer = csv.writer(file)
    csv_writer.writerow(['Value 1', 'Value 2', 'Value 3'])
