Why do all the radiobuttons start selected, and how do I stop that?

Below is my code. i would like to know how to start the program with the radio buttons not selected.
from tkinter import *
root = Tk()
root.title("Early Learning Tool")
root.geometry("800x400")
frame = LabelFrame(root, text="Letters", padx=30, pady=10)
frame.pack()
photo_A = PhotoImage(file=r"Pictures\A.png")
photo_B = PhotoImage(file=r"Pictures\B.png")
photo_C = PhotoImage(file=r"Pictures\C.png")
photo_D = PhotoImage(file=r"Pictures\D.png")
photo_E = PhotoImage(file=r"Pictures\E.png")
letter_choice = StringVar()
rb_A = Radiobutton(frame, variable=letter_choice, value="A", image=photo_A)
rb_A.grid(row=0, column=0)
rb_B = Radiobutton(frame, variable=letter_choice, value="B", image=photo_B)
rb_B.grid(row=0, column=1)
rb_C = Radiobutton(frame, variable=letter_choice, value="C", image=photo_C)
rb_C.grid(row=0, column=2)
rb_D = Radiobutton(frame, variable=letter_choice, value="D", image=photo_D)
rb_D.grid(row=0, column=3)
rb_E = Radiobutton(frame, variable=letter_choice, value="E", image=photo_E)
rb_E.grid(row=0, column=4)
root.mainloop()
This is what appears. How do I make it so it doesn't do that?

In letter_choice variable you have to set a default value in StringVar()
like so:
letter_choice = StringVar(value="A")

You need to initialize the StringVar with value other than empty string (default value if not specified) or the values for those radiobuttons, for example ' ':
letter_choice = StringVar(value=' ')

I tried running the programming switching the images to text.
from tkinter import *
root = Tk()
root.title("Early Learning Tool")
root.geometry("800x400")
frame = LabelFrame(root, text="Letters", padx=30, pady=10)
frame.pack()
letter_choice = StringVar()
rb_A = Radiobutton(frame, variable=letter_choice, value="A", text="A")
rb_A.grid(row=0, column=0)
rb_B = Radiobutton(frame, variable=letter_choice, value="B", text="B")
rb_B.grid(row=0, column=1)
rb_C = Radiobutton(frame, variable=letter_choice, value="C", text="C")
rb_C.grid(row=0, column=2)
rb_D = Radiobutton(frame, variable=letter_choice, value="D", text="D")
rb_D.grid(row=0, column=3)
rb_E = Radiobutton(frame, variable=letter_choice, value="E", text="E")
rb_E.grid(row=0, column=4)
root.mainloop()
I didn't encounter any problems. Indeed, the default radiobutton when no buttons are clicked, appears with a small grey dot. But when clicking on a radiobutton the default grey dots disappear.

why am i getting "TypeError: tuple indices must be integers or slices, not str", i am following a tutorial (python-tkinter and sqlite)

This is supposed to be a pet company administration GUI app made with tkinter
I am following a tutorial, I don't know why I'm getting this error but the tutor isn't getting it.
I have tried changing the string to int but it's still giving me an error
The program runs when the database is empty, I get this error only when I have data in my database

I want to take user input and output it inside GUI

I want to take user input and output it inside GUI ...
my code
from tkinter import *
root = Tk()
root.geometry("644x344")
def printSomething():
label = Label(root, text="???")
label.grid(row=1, column=2)
ok=Label(root, text="Type your name").grid(row=2,column=1)
entryvalue = StringVar()
entry= Entry(root, textvariable=entryvalue)
entry.grid(row=2, column=2)
button = Button(root, text="Print Me", command=printSomething)
button.grid(row=3, column=2)
root.mainloop()

To get the text from an input box, use inputbox.get(). Also, don't set the ok variable to Label(root, text="Type your name").grid(row=2,column=1). This will be set as NoneType, so do
ok = Label(root, text="Type your name").grid(row=2,column=1)
ok.grid(row=2, column=1)
Here is your code:
from tkinter import *
root = Tk()
root.geometry("644x344")
def printSomething():
label = Label(root, text=entry.get())
label.grid(row=1, column=2)
ok=Label(root, text="Type your name")
ok.grid(row=2,column=1)
entryvalue = StringVar()
entry= Entry(root, textvariable=entryvalue)
entry.grid(row=2, column=2)
button = Button(root, text="Print Me", command=printSomething)
button.grid(row=3, column=2)
root.mainloop()

First thing, In order to accept and display the output on the screen you have to use either Label widget or Canvas Text. Since your code is not updating the Label widget thus I am here doing what you want to do.
First, create a Label widget in the main window,
Get the user input by using.get() method,
print and display the user input.
from tkinter import *
root = Tk()
root.geometry("644x344")
def printSomething():
label.config(text=entry.get())
ok=Label(root, text="Type your name")
ok.grid(row=2,column=1)
entryvalue = StringVar()
entry= Entry(root, textvariable=entryvalue)
entry.grid(row=2, column=2)
button = Button(root, text="Print Me", command=printSomething)
button.grid(row=3, column=2)
#Create a Label to print the Name
label= Label(root, text="", font= ('Helvetica 14 bold'), foreground= "red3")
label.grid(row=1, column=2)
root.mainloop()

How do I print the random outcome of an entry input in a list?

Code
list = [ee1.get(), ee2.get(), ee3.get(), ee4.get(), ee5.get(), ee6.get(), ee7.get(), ee8.get(), ee9.get(), ee10.get()]
context = "What does", random.choice(list),"mean?"
labelquestion = Label(window, text = context, font = "Serif 10 bold")
Question
When I run this, it outputs "{What does} {} mean?"
How can I fix this so that it outputs "What does"-random entry from list-"this mean?"
(The things in the list are entries)

Below is an example based on your code and information in the comment:
import tkinter as tk
import random
window = tk.Tk()
ee1 = tk.Entry(window)
ee1.grid(row=0, column=0)
ee2 = tk.Entry(window)
ee2.grid(row=0, column=1)
ee3 = tk.Entry(window)
ee3.grid(row=0, column=2)
ee4 = tk.Entry(window)
ee4.grid(row=0, column=3)
ee5 = tk.Entry(window)
ee5.grid(row=0, column=4)
ee6 = tk.Entry(window)
ee6.grid(row=1, column=0)
ee7 = tk.Entry(window)
ee7.grid(row=1, column=1)
ee8 = tk.Entry(window)
ee8.grid(row=1, column=2)
ee9 = tk.Entry(window)
ee9.grid(row=1, column=3)
ee10 = tk.Entry(window)
ee10.grid(row=1, column=4)
def submit():
words = [ee1.get(), ee2.get(), ee3.get(), ee4.get(), ee5.get(),
ee6.get(), ee7.get(), ee8.get(), ee9.get(), ee10.get()]
context = f"What does '{random.choice(words)}' mean?"
labelquestion.config(text=context)
tk.Button(window, text="Submit", command=submit).grid(row=2, column=0, sticky='w')
labelquestion = tk.Label(window, font="Serif 10 bold")
labelquestion.grid(row=2, column=1, columnspan=4)
window.mainloop()

please help me solve this .

namee.grid(row=1, column=3)
phonee = Entry(win, textvariable=phonevar)
phonee.grid(row=2, column=3)
gendee = Entry(win, textvariable=gendervar)

emergencye = Entry(win, textvariable=emergencyvar)
emergencye.grid(row=4, column=3)
paymente = Entry(win, textvariable=paymentvar)
paymente.grid(row=5, column=3)
don't assign the variable in strings. here's the change.
It's just a suggestion
use :
a=Entry(..)
a.grid(..)
instead of
a=Entry(...).grid(...)
