批量提取下载地址从许多txt到一个新的txt文件

import re

# 存储下载地址的列表
download_urls = []

# 遍历所有的txt文件
txt_files = ["file1.txt", "file2.txt", "file3.txt"]
for file in txt_files:
    with open(file, "r") as f:
        # 逐行读取文件内容
        for line in f:
            # 使用正则表达式匹配下载地址的模式
            pattern = r"(http[s]?://(?:[a-zA-Z]|[0-9]|[$-_@.&+]|[!*\\(\\),]|(?:%[0-9a-fA-F][0-9a-fA-F]))+)"
            matches = re.findall(pattern, line)
            
            # 将匹配到的下载地址添加到列表中
            download_urls.extend(matches)

# 将下载地址保存到新的txt文件中
output_file = "download_urls.txt"
with open(output_file, "w") as f:
    for url in download_urls:
        f.write(url + "\n")

print("下载地址已保存到文件：", output_file)
