Viewing and Interact with function that requires User input in Tkinter - python-3.x

Question

I am Creating an App with Tkinter and for the App I need to use a function in a package that requires user input. I am trying to use sys.stdout in a thread and outputting sys.stdout to a Listbox() this works for another function of mine doing like the same thing but there isn't any user input. In the first line of this thread I am changing a button then doing the operation, and the button doesn't change and the App goes into non-responsive. My question is will the sys.stdout send what the input is asking? and How do I have user input from entry box send to the function while it is still running in the thread? Thanks in advance
Truncated code bellow:
class Login(tk.Frame):
def __init__(self,parent,controller):
tk.Frame.__init__(self,parent)
global Key
global button1
Key = tk.StringVar()
#Buttton to start thread
button1 = ttk.Button(self, text='Login',command=lambda:Setupthread2(lbx,button1,Key,KeyEntry))
button1.pack()
#Entry for user to input
KeyEntry = tk.Entry(self, show= '*', textvariable=Key)
KeyEntry.pack()
scb = tk.Scrollbar(self)
scb.pack(fill='y' ,side='right')
lbx = tk.Listbox(self, yscrollcommand=scb.set)
lbx.pack()
scb.config(command=lbx.yview)
def Setupthread2(object,button1,Key,KeyEntry):
global flag
send_process = threading.Thread(target=callback(object,button1,Key,KeyEntry))
send_process.start()
flag = False
def callback(object,button1,Key,KeyEntry):
#Changing the button so I can use the same button for both starting the tread and to send to sample func
button1.config(text = 'Send Code', command = lambda:SendUsrInput(Key,KeyEntry))
old_stdout = sys.stdout
sys.stdout = StdoutRedirectorLabel(object)
sample()
sys.stdout = old_stdout
#After Output finished set scrollbar to bottom
object.yview_moveto(1.0)
class StdoutRedirectorLabel(object):
def __init__(self,widget):
self.widget = widget
def write(self,text):
self.widget.insert('anchor',text)
# Me trying to send what they type in entry box to function
def SendUsrInput(Key,KeyEntry):
Key = Key.get()
print(Key)
KeyEntry.delete(0,'end')
#Truncated version of the function I need to show console and to send input to
def sample():
usrInput = input('Enter Input to get something Back')
print(usrInput + ' Was my input')

So in the module where it asks for user input with help I made a Tk window asking for input with a timeout using after()
def sample()
sms_code = loginTimeout()
def loginTimeout():
root = tk.Tk()
sms_code = ''
def get_entry() -> str:
"""Gets and returns the entry input, and closes the tkinter window."""
nonlocal sms_code
sms_code = entry_var.get()
root.destroy()
return sms_code
# Your input box
entry_var = tk.StringVar()
tk.Tk.wm_title(root,'Trading Bot')
tk.Label(root, text='Please Enter the Authorization Code').pack()
tk.Entry(root, textvariable=entry_var).pack()
# A button, or could be an event binding that triggers get_entry()
tk.Button(root, text='Confirm', command=get_entry).pack()
# This would be the 'timeout'
root.after(300000, get_entry)
root.mainloop()
return sms_code
