如何跳过行，直到找到txt文件中的‘关键字’，并将rest保存为csv？python

import csv

def find_keyword_and_save_as_csv(file_path, keyword, output_file):
    with open(file_path, 'r') as file:
        lines = file.readlines()

    found = False
    rest_lines = []
    for line in lines:
        if keyword in line:
            found = True
            continue
        if found:
            rest_lines.append(line)

    with open(output_file, 'w', newline='') as csv_file:
        writer = csv.writer(csv_file)
        for line in rest_lines:
            writer.writerow([line.strip()])

# 调用示例
file_path = 'input.txt'  # 输入的txt文件路径
keyword = '关键字'  # 要查找的关键字
output_file = 'output.csv'  # 输出的csv文件路径

find_keyword_and_save_as_csv(file_path, keyword, output_file)
