为什么Python从第二行开始写入我的CSV文件？

Question

我正在尝试创建一个值列表，以后可以稍后阅读，排序和搜索它们。虽然当我写入我的csv文件时，它会跳过第一行并在下一行打印。

我内心和外部都在寻找解决方案，但没有任何帮助。

这是我的代码：

from tkinter import *
import csv

window=Tk()

def show_entry_fields():
    with open('shoplist.csv', 'a') as csvfile:
        list = csv.writer(csvfile, delimiter=',', lineterminator='\n')
        list.writerow([ "%s" % (e3.get()) "%s" % (e4.get()), "%s" % (e5.get())])

Button(window, text='Add', command=show_entry_fields).grid(row=3, column=3)

v = StringVar()
e3 = Entry(window)
e4 = Entry(window)
e5 = Entry(window)
e3.grid(row = 3, column = 1)
e4.grid(row = 4, column = 1)
e5.grid(row = 5, column = 1)

l3 = Label(window, text = "Name:")
l3.grid(row = 3, column = 0)
l4 = Label(window, text = "Location:")
l4.grid(row = 4, column = 0)
l5 = Label(window, text = "Rate /5:")
l5.grid(row = 5, column = 0)
