如何在不删除之前数据的情况下将 append 新数据放入 my.csv 文件中

Question

I made a maths quiz where the program asks and stores the user's name, the question, the solution and the user's score into a.csv file. My problem is that whenever the program is run the newly inputted data overwrites the previous data set, which I don't want so instead I want the new data to be appended below the old data set. How can I do this?

Here is my code so far:

import csv
import random

Name = input("Enter your name: ")
score = 0

a = random.randint(1,100)
b = random.randint(1,100)
Q1 = int(input(str(a) + " + " + str(b) + " = "))
A1 = a + b

x = random.randint(1,100)
y = random.randint(1,100)
Q2 = int(input(str(x) + " - " + str(y) + " = "))
A2 = x - y

if Q1 == A1:
    score1 = score + 1
else:
    score1 = score


if Q2 == A2:
    score2 = score + 1

else:
    score2 = score

with open("Quiz.csv", "w", newline="") as file:
    writer = csv.writer(file)
    writer.writerow([Name, "Question", "Solution", "Mark"])

    writer.writerow([1, str(a) + " + " + str(b) , A1, score1])
    writer.writerow([2, str(x) + " - " + str(y) , A2, score2])

You need to open the file in append mode, like this:

with open("Quiz.csv", "a", newline="") as file:
