import csv

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

new_column = ['value1', 'value2', 'value3']  # 新列的数据
for i in range(len(data)):
    data[i].append(new_column[i])  # 将新列数据添加到每一行的末尾

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

import csv

    reader = csv.reader(file)
    data = list(reader)

new_column = ['value1', 'value2', 'value3']  # 新列的数据
for i in range(len(data)):
    data[i].append(new_column[i])  # 将新列数据添加到每一行的末尾

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