从CSV中读取值到python中，创建新的值，如何将其添加到新行？

import csv
import pandas as pd

with open('file.csv', 'r') as file:
    reader = csv.reader(file)
    data = list(reader)

new_value = 10  # 假设创建的新值为10

new_row = [new_value]  # 创建包含新值的新行
data.append(new_row)  # 将新行添加到数据列表中

with open('new_file.csv', 'w', newline='') as file:
    writer = csv.writer(file)
    writer.writerows(data)

import csv

# 从CSV中读取值
with open('file.csv', 'r') as file:
    reader = csv.reader(file)
    data = list(reader)

# 创建新的值
new_value = 10

# 将新值添加到新行
new_row = [new_value]
data.append(new_row)

# 将更新后的数据写入新的CSV文件
with open('new_file.csv', 'w', newline='') as file:
    writer = csv.writer(file)
    writer.writerows(data)
