Answer:

Translating the provided AutoIt script into Python without using external libraries involves re-implementing the core functionalities such as file hashing, process management, and window interaction. Below is a Python version that captures the essence of the original AutoIt script. Note that some functionalities, especially those related to Windows API, may require a more complex implementation in Python, and certain features may not be directly translatable without external libraries.

Here's a simplified version of the AutoIt script in Python:

import os
import hashlib
import subprocess
import time
import ctypes
from ctypes import wintypes

# Constants
PROCESS_ABOVENORMAL = 0x4000
EVENT_SYSTEM_MENUEND = 0x8001

# Function to calculate SHA1 hash of a file
def hash_file(filepath):
    if not os.path.exists(filepath):
        return None
    hasher = hashlib.sha1()
    with open(filepath, 'rb') as f:
        while chunk := f.read(8192):
            hasher.update(chunk)
    return hasher.digest()

# Function to check if a process is running
def process_exists(process_name):
    try:
        # Get a list of all running processes
        process_list = subprocess.check_output(['tasklist']).decode().splitlines()
        for process in process_list:
            if process_name in process:
                return True
    except Exception as e:
        print(f"Error checking process: {e}")
    return False

# Function to close a process by name
def close_process(process_name):
    try:
        subprocess.call(['taskkill', '/F', '/IM', process_name])
    except Exception as e:
        print(f"Error closing process: {e}")

# Function to launch a process
def launch_process(executable, *args):
    try:
        return subprocess.Popen([executable] + list(args))
    except Exception as e:
        print(f"Failed to start {executable}: {e}")
        return None

# Main script logic
def main():
    dependencies = {
        'RoboTarot.swf': b'\xf6\x96\xf4\x91\xbd\x65\x37\x03\x48\x9c\x7a\x68\x5c\x29\xd7\x22\xc4\xfb\x7c\xef',
        'SAFlashPlayer.exe': b'\x90\x0c\x97\x82\x87\x0d\x97\x33\x93\xcf\xb3\x2d\xf0\x4b\xef\xc7\x72\x97\x82\x8'
    }

    working_dir = os.getcwd()

    for filename, expected_hash in dependencies.items():
        file_path = os.path.join(working_dir, filename)
        if not os.path.exists(file_path):
            print(f"File {filename} not found at path {working_dir}.")
            return

        file_hash = hash_file(file_path)
        if file_hash is None:
            print(f"Failed to obtain the SHA1 hash of the file {filename}.")
            return

        if file_hash != expected_hash:
            print(f"SHA1 hash of the file {filename} is different from the expected value.")
            return

    # Close existing instances of SAFlashPlayer.exe
    if process_exists('SAFlashPlayer.exe'):
        close_process('SAFlashPlayer.exe')

    # Launch SAFlashPlayer.exe
    process = launch_process(os.path.join(working_dir, 'SAFlashPlayer.exe'), os.path.join(working_dir, 'RoboTarot.swf'))
    if process is None:
        return

    # Monitor the process
    while True:
        if process.poll() is not None:  # Process has exited
            print("Process SAFlashPlayer.exe has stopped working.")
            break

        # Here you would normally check for window events, but this is complex in Python without external libraries
        time.sleep(0.1)

if __name__ == "__main__":
    main()

Key Points:

  1. File Hashing: The hash_file function computes the SHA1 hash of a file using Python's built-in hashlib.
  2. Process Management: The script checks for running processes and can close them using taskkill.
  3. Launching Processes: The launch_process function starts a new process using subprocess.Popen.
  4. Window Interaction: The original AutoIt script interacts with windows and menus, which is complex in Python without libraries like pywin32. This part is omitted for simplicity.

Limitations:

  • The script does not handle window events or menu interactions, as this would require a more complex setup in Python.
  • Error handling is basic and can be expanded for robustness.
  • The script assumes it is running in a Windows environment due to the use of Windows-specific process management commands.
