Python Tkinter button invalid syntax error

You are missing a parenthesis on:

questionEntry.grid(row = 1, column = 0

it should be:

questionEntry.grid(row = 1, column = 0)

There is two error in your code and its a simple error: 1- questionEntry.grid(row = 1, column = 0)

2- In the end line you have to call the funtion named as QuestionMenu()

and i am giving the whole code with proper solution and runnable code:

import sqlite3
from tkinter import ttk
import tkinter
from tkinter import messagebox

with sqlite3.connect("question.db") as db:
    cursor = db.cursor()

cursor.execute("""CREATE TABLE IF NOT EXISTS game (
                questionID integer PRIMARY KEY AUTOINCREMENT,
                question text,
                answer text
                )""")

    c.execute("INSERT INTO game VALUES (?, ?, ?)", (emp))
    conn.commit()

def get_question():
    c.execute("SELECT * FROM game")
    return c.fetchall()

def remove_question(emp):
    c.execute("DELETE from game WHERE question = ?", [emp])
    conn.commit()

def showInstructions():
    messagebox.showinfo("Instructions", """You are a treasure hunter, your goal is to collect atleast 100
gold by the end of the game from treasure chests randomly scattered across the grid.There are 10 chests within a grid and
each treasure chest is worth 10 gold but can only be reclaimed 3 times before it is replaced by a bandit.
Landing on a bandit will cause you to lose all of your
gold and if all the chests have been replaced by bandits and you have less then 100 gold this means you lose!
