Python Tkinter button invalid syntax error

Question

Whenever I run this code I keep on receiving a syntax error regarding this code line:

btn = ttk.Button(window, text="Submit", command=lambda: removeQuestion(DeleteQuestion))

I have looked at changing the parameters, variable names and more yet I still keep on getting this error and I am not sure what is wrong.

Full code:

Answer 1

You are missing a parenthesis on:

questionEntry.grid(row = 1, column = 0

it should be:

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

Answer 2

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
                )""")

#SQL QUESTION ADD/REMOVE/GET
def insert_question(emp):
    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()

#Tkinter
def showInstructions():
    messagebox.showinfo("Instructions", """You are a treasure hunter, your goal is to collect atleast 100
