python .get 函数添加了一个换行符，我该如何删除它？

Question

I am using the tkinter add on within python and I am ".get"ing input text from a text widget,

When i do so it decides to add a newline.

I don't want this newline because it messes with my CSV savefile and means i cants read my CSV file properly from python.

how do i get rid of the "\\n"?

I have tried ".rstrip" and ".splitlines" neither work.

This is what is displayed by the code...

How do i get rid of the newline "\\n"?

Pure code:

TextIDNumber = Text(App, height = "1", width = "25", bd = "4")
TextIDNumber.place(x = 550, y = 250)
TextIDNumber.config(font =("bold", 20))
TextSurname = Text(App, height = "1", width = "25", bd = "4")
TextSurname.place(x = 550, y = 350)
TextSurname.config(font =("bold", 20))



def CheckInputUI():
    IDNumber = TextIDNumber.get("1.0", END)
    Surname = TextSurname.get("1.0", END)
    print (Surname, IDNumber)
    print ("")
    print (Surname + IDNumber)

The shortest possible code that reproduces your problem, that we can run on our own machines:

from tkinter import *


App = Tk()

#This maximises the window
w = App.winfo_screenwidth()
h = App.winfo_screenheight()

App.geometry("%dx%d+0+0" % ((w-10), (h-30)))

TextIDNumber = Text(App, height = "1", width = "25", bd = "4")
TextIDNumber.place(x = 550, y = 250)
TextIDNumber.config(font =("bold", 20))
TextSurname = Text(App, height = "1", width = "25", bd = "4")
TextSurname.place(x = 550, y = 350)
TextSurname.config(font =("bold", 20))

def PrintInfo():
    IDNumber = TextIDNumber.get("1.0", END)
    Surname = TextSurname.get("1.0", END)
    print (Surname, IDNumber)
    print ("")
    print (Surname + IDNumber)

DoneButton = Button(App, text = " Done ", font = ("bold", 18), command = PrintInfo).place(x = 400,y = 800)

I use the prints to display my work to the shell only (so i could find the root of the problem, in other words where the newlines where being added), they server no other purpose.

The text widget guarantees that there is always a newline at the end, even if there isn't one in the actual data. To get the all of the data from the widget except this special newline, use "end-1c" (end minus one character) when getting the data:

IDNumber = TextIDNumber.get("1.0", "end-1c")
Surname = TextSurname.get("1.0", "end-1c")

If there's a chance that blank lines will get added to the data, you can strip off all trailing whitespace with strip :

IDNumber = TextIDNumber.get("1.0", END).rstrip()
Surname = TextSurname.get("1.0", END).rstrip()
