如何从CSV文件中删除一些行和列并保存到新的CSV？

import csv

def delete_rows_and_columns(input_file, output_file, rows_to_delete, columns_to_delete):
    with open(input_file, 'r') as file:
        reader = csv.reader(file)
        data = list(reader)

    # 删除指定的行
    for row_index in sorted(rows_to_delete, reverse=True):
        del data[row_index]

    # 删除指定的列
    for row in data:
        for column_index in sorted(columns_to_delete, reverse=True):
            del row[column_index]

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

# 示例用法
input_file = 'input.csv'
output_file = 'output.csv'
rows_to_delete = [1, 3]  # 要删除的行的索引，从0开始计数
columns_to_delete = [2, 4]  # 要删除的列的索引，从0开始计数

delete_rows_and_columns(input_file, output_file, rows_to_delete, columns_to_delete)
