如何将一个文本文件拆分为多个文件？

Question

我提取了一个具有以下格式的文本文件：

我需要按每个换行符拆分文件以接收以用户（1,4）命名且仅包含 ansible 秘密的文件。

我尝试过的方法：

from sys import argv

with open(argv[1], "r") as file:
    for line in file:
        fname = ""
        secret = []

        if line.startswith("user"):
            fname = line

        elif line.startswith("\\$ANSIBLE"):
            secret.append(line)

        elif line[0].isdigit():
            secret.append(line)

        elif len(line.strip()) == 0:
            f = open(fname, "x")
            for i in secret:
                f.write(i)
            f.close()
        
        else:
            print("This is not supposed to happen.)"

到目前为止，我遇到了 SyntaxError: Unexpected EOF while parsing ，感觉这是最低效的方法。

Answer 1

print("This is not supposed to happen.)"
                                     # ^ typo here!
