如何使用Python在同一CMD窗口中随机运行文件夹内的.bat文件并循环执行Python脚本

Got it, let's sort this out for you! The issue with the solution you tried is that it spawns a new CMD window—we can fix that by tweaking how we run the .bat file and restart the script, all within the same terminal session.

Here's a complete Python script that does exactly what you need: picks a random .bat from your target folder, runs it in the same CMD window, then restarts itself once the .bat finishes.

Full Code #

import os
import random
import subprocess
import sys

def get_random_bat_file(bat_directory):
    # Grab all .bat files from the specified folder (case-insensitive)
    bat_files = [
        filename 
        for filename in os.listdir(bat_directory) 
        if filename.lower().endswith(".bat")
    ]
    
    if not bat_files:
        print("Error: No .bat files found in the target folder!")
        sys.exit(1)
    
    # Return full path to a randomly selected .bat
    return os.path.join(bat_directory, random.choice(bat_files))

if __name__ == "__main__":
    # Replace this with your actual folder path (use raw string to avoid escape issues)
    TARGET_BAT_FOLDER = r"C:\Path\To\Your\Bat\Files"
    
    # Get our random .bat file
    selected_bat = get_random_bat_file(TARGET_BAT_FOLDER)
    print(f"Starting execution of: {selected_bat}\n")
    
    # Run the .bat file in the same CMD window, wait for it to finish
    try:
        # shell=True ensures the .bat is parsed correctly by Windows command shell
        subprocess.run(selected_bat, check=True, shell=True)
        print("\n.bat file executed successfully!")
    except subprocess.CalledProcessError as e:
        print(f"\nError running .bat file: {e}")
    
    # Restart the current Python script in the same window
    print("\nRestarting Python script now...")
    subprocess.run([sys.executable] + sys.argv)

Key Details Explained #

• Running the .bat in the same window: We use subprocess.run() without any creationflags (like CREATE_NEW_CONSOLE) that would spawn a new window. This ensures the .bat runs directly in the existing CMD session, and the script waits until it finishes before moving on.
• Restarting the script: sys.executable gets the path to your current Python interpreter, and sys.argv captures all the original command-line arguments used to start the script. Combining these lets us restart the script exactly as it was launched.
• Error handling: The try-except block catches any errors from the .bat file (like non-zero exit codes) so the script doesn't crash unexpectedly. You can modify this to skip restarting if the .bat fails, if that's what you want.

Quick Setup Tips #

1. Replace TARGET_BAT_FOLDER with the full path to your folder of .bat files. Use a raw string (prefix with r) to avoid issues with backslashes (e.g., r"C:\MyBats" instead of "C:\\MyBats").
2. Make sure your Python script has permission to read the target folder and execute the .bat files.
3. If you want to test without looping endlessly, you can add a condition to skip restarting (like a counter or a command-line flag).
