How can I destroy the buttons generated using a for loop (after been clicked)

Question

I already generated the buttons which their name is based on the list output1.

So, This program will create 4 buttons respectively from ‘key1’ to ‘key4’
, whenever I click the button key1, the search box B will be replaced by "key1"
,similarly, button key 2,key3,key4 will replace "key2","key3","key4" respectively in search box B…

My objective is once I click one of these buttons, It will insert the word in the seach box B, and these 4 buttons will automatically be deleted

root = Tk()

def setTextInput(text):
    B.delete(0,"end")
    B.insert(0, text)
    for k in Autput1:
        Autput1[k].destroy()    

j=0

if j==0:

    output1 = ['key1','key2','key3','key4']
    
    global Autput1
    Autput1 = []
    
    k=0
    
    for e in output1:                                                                                             
        Autput1.append(Button(root,text=e,command=lambda e=e:setTextInput(str(e))))
        Autput1[k].grid()
        print(Autput1)
        k+=1

A = Label(root,text="Search your song here",font=('Roboto',10),bg='#c4302b')
A.grid(row=0,column=0,columnspan=2,padx=10,pady=10)

B = Entry(root,font=('Roboto',20))
B.grid(row=1,column=0,columnspan=2,padx=10,pady=10)

C= Button(root,image=img,command=getsong)
C.grid(row=1,column=2,padx=10,pady=10)

root.mainloop()

This is the part of how I try to destroy the button which appends inside the list Autput1.

  for k in Autput1:
    Autput1[k].destroy()

and This is the error and the only problem I try to fix

 TypeError: list indices must be integers or slices, not Button

You might be wondering what is the value Autput1

   [<tkinter.Button object .!button2>, <tkinter.Button object .!button3>, <tkinter.Button object 
   .!button4>, <tkinter.Button object .!button5>]

In order to make buttons in a loop you need to either use partial for the command:

from functools import partial
# ...
for e in output1:                                                                                             
    Autput1.append(Button(root,text=e,command=partial(setTextInput, e)))

Or bind the data to lambda with a default argument:

for e in output1:                                                                                             
    Autput1.append(Button(root,text=e,command=lambda data=str(e):setTextInput(data)))

My problem is now solved! I just changed this line.
Thank you to Novel!

for e in output1:                                                                                             
     Autput1.append(Button(root,text=e,command=lambda data=str(e):setTextInput(data)))

Also, ‘change lambda to lambda e=e’ also helped solving my problem

for e in output1:     
     Autput1.append(Button(root,text=e,command=lambda e=e:setTextInput(str(e))))
