如何保存输入的文本？（Python）

我对python和一般的编码都是新手。我想知道你如何将回答问题的文本保存到文本文件中。这是一本日记，所以每次我写下东西并单击“添加”时，我都希望它添加到文本文件中

cue = Label(text="What happened?")
cue.pack()

e_react = StringVar()
e = Entry(root, textvariable=e_react, width=40, bg="azure")
e.pack()

def myclick():
    cue = "Cue: " + e.get()
    myLabel = Label(root, text=cue, bg="azure")
    myLabel.pack()

myButton = Button(root, text="Add", command=myclick)
myButton.pack()

react = Label(text="How did you react?")
react.pack()

e1 = Entry(root, width=40, bg="azure")
e1.pack()


def myclick():
    react = "Reacted by: " + e1.get()
    myLabel = Label(root, text=react, bg="azure")
    myLabel.pack()

myButton = Button(root, text="Add", command=myclick)
myButton.pack()

f = open("Hey.txt", "a")
f.write(e_react.get())
f.close()

我尝试将其保存为字符串变量，但它说我无法为附加文件执行此操作

非常感谢

这就是你需要的吗

from tkinter import *


root = Tk()
root.title("MyApp")

cue = Label(text="What happened?")
cue.pack()

e_react = StringVar()
e = Entry(root, textvariable=e_react, width=40, bg="azure")
e.pack()

def myclick():
    cue = "Cue: " + e.get()
    myLabel = Label(root, text=cue, bg="azure")
    myLabel.pack()
    f = open("Hey.txt", "a")
    f.write(e.get() + "\n")
    f.close()


myButton = Button(root, text="Add", command=myclick)
myButton.pack()

react = Label(text="How did you react?")
react.pack()

e1 = Entry(root, width=40, bg="azure")
e1.pack()


def myclick():
    react = "Reacted by: " + e1.get()
    myLabel = Label(root, text=react, bg="azure")
    myLabel.pack()
    f = open("Hey.txt", "a")
    f.write(e1.get() + "\n")
    f.close()

myButton = Button(root, text="Add", command=myclick)
myButton.pack()



root.mainloop()

关键是使用StringVar.get（）方法，正如在接受的答案中所使用的那样。@TerryJanReedy:StringVar在这里是完全可选的。在小部件本身上调用

get（）

也会起到同样的作用。如果您添加了对您所做不同操作的描述，这个答案会更好。否则，我们必须逐行和逐字符地将此代码与原始代码进行比较。
