[Tutor] Can I shorten this code?

[Mic]

Hi!
I am new to programming and it have recently come to my attention that alot 
of my code could be shortened.
I have managed to shorten some of the code, but I ran into a problem with 
this piece of code:


#Testing changing color and text on two buttons in a GUI.

from tkinter import*

value1=("green")
click1=1

value2=("green")
click2=1


class Window(Frame):
    def __init__(self,master):
        super (Window,self).__init__(master)
        self.grid()

        self.create_widgets()



    def create_widgets(self):

        #Creates hello button1
        self.hello_bttn1=Button(self,bg=value1)
        self.hello_bttn1["text"]="Hi_1"
        self.hello_bttn1["command"]=self.change_value_hellobttn1
        self.hello_bttn1.grid()


        #Creates hello button2
        self.hello_bttn2=Button(self,bg=value2)
        self.hello_bttn2["text"]="Hi_1"
        self.hello_bttn2["command"]=self.change_value_hellobttn2
        self.hello_bttn2.grid()



    def change_value_hellobttn1(self):

        def change_click():
            global click1
            click1*=-1

        change_click()

        if click1==-1:

            self.hello_bttn1.configure(bg="red")
            self.hello_bttn1.configure(text="Hi_2")


            def change_global1():
                global value1
                value1=("red")
            change_global1()




        elif click1==1:
            self.hello_bttn1["text"]="Hi_1"
            self.hello_bttn1.configure(bg="green")



            def change_global2_1():
                global value1
                value1=("green")
            change_global2_1()

            #-------------------------------------------------

    def change_value_hellobttn2(self):

        def change_click2():
            global click2
            click2*=-1

        change_click2()

        if click2==-1:

            self.hello_bttn2.configure(bg="red")
            self.hello_bttn2.configure(text="Hi_2")


            def change_global2():
                global value2
                value2=("red")
            change_global2()




        elif click2==1:
            self.hello_bttn2["text"]="Hi_1"
            self.hello_bttn2.configure(bg="green")



            def change_global2_2():
                global value2
                value2=("green")
            change_global2_2()


Imagine now that I want to do the same thing with 8 buttons, that I did to 
these two buttons. How would I shorten this?
Otherwise I repeat a lot of my code, and I would like to avoid that.

Thank you!
