python - 如何在txt文件的变量中写入字符串

Question

我有一个变量，其中包含一个字符串，我想使用 python 在 .txt 文件中写入该字符串。但我不知道该怎么做。e1是包含字符串的变量。

from tkinter import * 

root = Tk()
root.title("records manager")
root.geometry("600x200")

label0 = Label(root, text="")
label0.pack()
label1 = Label(root, text="Welcome to records manager (づ｡◕‿‿◕｡)づ", font=("ariel bold", 20))
label1.pack()

leftframe = Frame(root, padx="20", pady="20")
leftframe.pack(side=LEFT)
rightframe = Frame(root, padx="20", pady="20")
rightframe.pack(side=RIGHT)

def add():
    patients = open("Patients.txt", "a")
    e1 = Entry1.get()
    patients.write(e1 + "\n")
    patients.close()

New = Label(leftframe, text="New Patients", font=("ariel bold", 12))
New.grid(row=0)
Entry1 = Entry(leftframe, width=40, border=5)
Entry1.grid(row=0, column=1)
button1 = Button(rightframe, width=20, command=add(), text="Add")
button1.grid(row=0, column=0)

root.mainloop()
