AttributeError: module 'serial'has no attribute 'Serial'

hii guys,

I have this attributeError in my python script. when I start the .exe it will immediately close.
I am trying to get my Serial from my arduino in my python script. somebody knows how to solve this problem??

this is my arduino script:

#include <LiquidCrystal.h>
#include <Keypad.h>

const byte numRows= 4;
const byte numCols= 3;

LiquidCrystal lcd(8, 9, 7, 6, 5, 4);

char keymap[numRows][numCols]=
{
{'1','2','3'},
{'4','5','6'},
{'7','8','9'},
{'*','0','#'}
};

byte rowPins[numRows]= {13, 12, 11, 10};
byte colPins[numCols]= {3, 2, A1};

Keypad myKeypad= Keypad(makeKeymap(keymap), rowPins, colPins, numRows, numCols);

char key,action;
int count=0;

void setup(){
Serial.begin(9600);
lcd.begin(16, 2);
lcd.setCursor(0,0);
lcd.print("BOEKNUMMER:");

}

void loop(){

char key = myKeypad.getKey();

if (key){
lcd.print(key);
Serial.print(key);
}

if (key =='*'){
lcd.clear();
lcd.print("BOEKNUMMER:");
lcd.setCursor(0, 1);
Serial.write("ja");

}

if (key =='#'){
Serial.write("nee");

}
}

and this is my python script:

import webbrowser
import serial

from serial import serial

with serial.Serial('COM5', 9600) as ser:

b = ser.readline()

random = input ("Wilt U een boek opzoeken? Ja/Nee: ")
random2 = ("gewoon een random tekst")
print(b)
if random in ["*Ja", "*ja", "JA", "jA", "yes", "Yes"]:

boek_nmmr = input ("Geef hier Uw boek ID/ISBN nummer op: ")
print(b)

boek_id = int(boek_nmmr)
webbrowser.open('https://educatief.dedicon.nl/products/search?Zoeken='+ boek_nmmr)

random3 = input ("Wilt U stoppen met zoeken? Ja of Nee (toets een nummer in voor nee): ")
print(b)
if random3 in ["Ja", "ja", "JA", "jA", "yes", "Yes"]:
print("Oké, nog een fijne dag!")
break

else:
print("nog een fijne dag")

use

import serial

not

from serial import serial

remove the second from the script.
