Random String and Timestamp Check Function

The function first generates a random string of a specified length, then gets the current timestamp, checks if the specified file path exists, and finally returns the sum of the length of the string and the timestamp (if the file exists) or -1 (if the file does not exist).

    file_exists = os.path.exists(arg2)
    
    # 计算字符串长度与时间戳的数学和
    result = len(random_str) + timestamp
    
    # 如果文件存在，则返回计算结果，否则返回-1
    return result if file_exists else -1
