Can’t get the expected output of “dir” command using wexpect on python.

My wexpect script:

import wexpect

def run_cmd():
    # Start cmd.exe process
    cmd = wexpect.spawn("cmd.exe")

    # Display the initial prompt
    cmd.expect(">")
    print(cmd.before + ">", end="")

    while True:
        # Read user input
        user_input = input()
        
        # Exit loop if user types "exit"
        if user_input.lower() == "exit":
            cmd.sendline("exit")
            break

        # Send the user input to cmd.exe
        cmd.sendline(user_input+" && (echo commandend1 && echo commandend2) || (echo commandend1 && echo commandend2)")

        # Wait for the command to complete and print its output
        cmd.expect(r"(commandend1 rncommandend2rnrn(?:[^\]+\)*[^\]*>)")

        # Remove the first line of command output (user input)
        print("rn".join(cmd.before.split("rn")[1:]))

        prompt = cmd.after.replace("commandend1 rncommandend2rnrn", "")
        print(prompt, end="")

if __name__ == "__main__":
    run_cmd()

The expected output of my script (exactly the same as cmd.exe):
