来位大神救救孩子吧，一道文件类题

import re

# 读取输入文件
with open("trans.in", "r") as fin:
    input_str = fin.readline().strip()

# 正则表达式匹配连续的数字
pattern = re.compile(r"\d+")
numbers = pattern.findall(input_str)

# 写入输出文件
with open("trans.out", "w") as fout:
    fout.write(str(len(numbers)) + "\n")
    for num in numbers:
        fout.write(num + " ")
    fout.write("\n")

希望可以帮助到你
