I have written the following code but for some reasons the .get() gives me nothing.
I have tried printing fullname.get()'s len and it gives me 0 with following error:

There is no way for me to reproduce your error. I suspect it could be caused by import * or one of your bad get() methods. Likely the get() methods as you do not even set value of entry's text and probably getting the Null value from that.
Keep in mind you need to run the get() method inside of a function and not in the same location you are initializing your code.
One of the other major problems is the use of Tk() more than once. You always want to use only one instance of Tk() when building a Tkinter GUI. For new windows use Toplevel().
I have cleaned up your code to follow PEP8 more closely. Let me know if this helps.

There is code that checks the availability of sites.
How can we make the status for each site to change at a user defined time (i.e. the time for each site can be different) The problem is that the number of sites is not limited, because you can add more lines to the application, so I do not understand how to implement it.
I attach a picture of how it looks like:
Code:
import tkinter as tk
from tkinter import ttk
import requests
import time
from tkinter import *
from tkinter import messagebox
data_list = []
window = Tk()
window.geometry('400x700')
window.title("SiteChecker")
def set_input(obj, value):
obj.delete(1.0, "END")
obj.insert("END", value)
def SiteCheck():
# time.sleep
for data in data_list:
url = data[0].get()
status = data[2]
if not str(url).startswith('http'):
continue
print(url)
Get_Response = None
try:
Get_Response = requests.get(url)
except:
status.config(text='status bad')
continue
if Get_Response.status_code == 200:
status.config(text='status ok')
pass
implement
else:
status.config(text='status bad')
def clicked():
txt = Entry(window, width=18)
txt.grid(column=0, pady=8)
txt_row = txt.grid_info()['row']
tim = Entry(window, width=3)
tim.grid(row=txt_row, column=1, pady=8)
txt_row = tim.grid_info()['row']
result1 = Label(window, text="status")
result1.grid(row=txt_row, column=2, pady=8)
data_list.append([txt, tim, result1])
lbl1 = Label(window, text="Enter references:")
lbl1.grid(column=0, row=1)
lbl2 = Label(window, text="Enter the test time: ")
lbl2.grid(column=1, row=1)
lbl3 = Label(window, text="Availability status ")
lbl3.grid(column=2, row=1)
for loop in range(2, 6):
txt1 = Entry(window, width=18)
txt1.grid(column=0, row=loop, pady=8)
tim1 = Entry(window, width=3)
tim1.grid(column=1, row=loop, pady=8)
result1 = Label(window, text="status")
result1.grid(column=2, row=loop, pady=8)
data_list.append([txt1, tim1, result1])
btn = Button(window, text="Add another site", command=clicked)
btn.grid(column=1, row=0)
Check_Button = Button(
window,
command=SiteCheck,
text='Start checking',
)
Check_Button.grid(row=0, column=2)
window.mainloop()
See here (How do I make my function run every second) how to use tkinter after() to achieve what you want. time.sleep won't work for your purpose because it is blocking the execution of the entire code.
From the link given in the comment to your question by Patrick Artner :
Tkinter root windows have a method called after() which can be used to schedule a function to be called after a given period of time. If that function itself calls after() you've set up an automatically recurring event.
i am building a google translator with tkinter and googletrans, and everything looks good and works well until i added the last part of it that handles what happens when you press the translator button, that is, this function:
def translate_now():
text_ = text1.get(1.0, END)
t1 = Translator()
trans_text = t1.translate(text_, src=combo1.get(), dest=combo2.get())
trans_text = trans_text.text
text2.delete(1.0, END)
text2.insert(END, trans_text)
it then gives me this error when i run it:

am suspecting it may be having problems connecting to google translator or something similar. but what could be the problem precisely?
you are getting this error because you dont have updated version of googletrans,
so use update version of googletrans :
Command to install update version: "pip install googletrans==3.1.0a0"
This will solve your problem.
I'm trying to build a very simple program in Python and Tkinter that allows the user to input people's names by keyboard and then a button is commanded to select a person from the list at random and show it in a tk.Label object.
My problem is once I run the root.mainloop(), I can add names to the list but the list does not update with the new names.
This is the main code for the Tkinter to initialize
import tkinter as tk
from tkinter import filedialog, Text
import random
root = tk.Tk()
root.title('Millor persona del moment')
root.geometry("500x200")
root.configure(bg='black')
peopleList = []
tk.Label(root, text="Insertar participante: ",fg="#ff007f", bg='black').grid(row=0)
e1 = tk.Entry(root)
e1.grid(row=0, column=1)
addButton = tk.Button(root, text='Añadir', padx=10, pady=5, fg="#ff007f", bg='black', command=addPerson)
addButton.grid(row=0, column=2)
while peopleList:
turnButton = tk.Button(root, text='Saca Tema', padx=10, pady=5, fg="#ff007f", bg='black', command=wordTurn(peopleList))
turnButton.grid(row=1, column=0)
nom = tk.StringVar()
nom.set('Comencem')
personSpeaking = tk.Label(root, textvariable=nom,fg="#ff007f", bg='black')
personSpeaking.grid(row=1, column=1)
root.mainloop()
And these are the functions I use
def addPerson():
peopleList.append(e1.get())
e1.delete(0,'end')
def wordTurn(peopleList):
person = random.choice(peopleList)
peopleList.remove(person)
nom.set(person)
command=wordTurn(peopleList)) calls the return value of wordTurn when the button is pressed, which is None and should raise an error. Use command=lambda peopleList=peopleList: wordTurn(peopleList)) instead.
relatively new to coding and currently I am playing with tkinter in python, I am using a text widget within a function and want to send the input from the text box to another function. My global variable says undefined at module level, so How could I make it defined at a module level if its within a function?
When I press the send email button I get this error message "NameError: name 'user_message_entry' is not defined"
Any suggestions? Many thanks!
minimum reproduction:
import tkinter as tk
root = tk.Tk()
root.geometry("500x500")
def send_email():
global user_message_entry
subject = ":)"
body = user_message_entry.get("1.0", "end")
message = f"subject: {subject}\n\n {body}"
print(message)
def feedback():
feedback_window = tk.Toplevel()
feedback_window.geometry("690x650")
message_frame = tk.Frame(feedback_window)
message_frame.grid(row=0, column=0, columnspan=3)
user_message_entry = tk.Text(message_frame, height=10, width=60)
user_message_entry.grid(row=0, column=0)
send_email_button = tk.Button(feedback_window, command=send_email,
height=20, width=20, bg="yellow", text="send email")
send_email_button.grid(row=1, column=0)
open_feedback_button = tk.Button(root, command=feedback, height=20, width=20, bg="yellow", text="open feedback window")
open_feedback_button.grid(row=1, column=0)
root.mainloop()
You can use Object orient methodology to make access sympler, another option also you can use globals() to make variable global
One way
globals()['user_message_entry'] = tk.Text(message_frame, height=10, width=60)
....
and from another function you can call
body = globals()['user_message_entry'].get("1.0", "end")
Second way
Object oriented programming is good for every type of problem solving, so you can use class as well
import tkinter as tk
class CBased:
def __init__(self, master, *args, **kwargs):
super(CBased, self).__init__(*args, *kwargs)
self.master = master
master.geometry("500x500")
self.open_feedback_button = tk.Button(master, command=self.feedback, height=20, width=20, bg="yellow", text="open feedback window")
self.open_feedback_button.grid(row=1, column=0)
def send_email(self):
subject = ":)"
body = self.user_message_entry.get("1.0", "end")
message = f"subject: {subject}\n\n {body}"
print(message)
def feedback(self):
self.feedback_window = tk.Toplevel()
self.feedback_window.geometry("690x650")
self.message_frame = tk.Frame(self.feedback_window)
self.message_frame.grid(row=0, column=0, columnspan=3)
self.user_message_entry = tk.Text(self.message_frame, height=10, width=60)
self.user_message_entry.grid(row=0, column=0)
self.send_email_button = tk.Button(self.feedback_window, command=send_email,
height=20, width=20, bg="yellow", text="send email")
self.send_email_button.grid(row=1, column=0)
def main():
root = Tk()
myobj = CBased(root)
root.mainloop()
if __name__ == "__main__":main()
In this way you can call every single item by self.xyz
Below is the the code that I currently have. I am beginner programmer and am writing a small program that will automate some workflow for primer design (biologist / bioinformaticists represent).
The issue I have right now is that my lack of understanding of how OOP works with TKinter. I have read numerous stackoverflow posts and watched youtube videos and read guides that try to explain it but I am still somewhat at a loss. My current understanding is that each window should be its own object, with the window above it as its parent. I've attempted to do this with my program.
Currently I have two classes, AUTOPRIMER, and BlastAPI. AUTOPRIMER is the main window. There is a button in that window that I have created that should open up a new window when clicked. From my understanding, I have created a new object for that window called BlastAPI which deals with that particular requirement of my program. I see many guides that suggest the parent should be put in the init of the new object, but there are so many initialization variations I have seen from parent to master to args*, kwargs**. What is appropriate when? Also, currently the stack trace provides this feedback as it doesn't even compile properly.

Thanks guys.
Ok so there is a lot that needs work here. I imagine the missing bits are part of your main code but without them testing your code is just not possible. I work with what I could and set up your class's to inherit from the tkinter objects they needed to be. Judging by your button command in your BlastAPI class I am assuming this class should be a Toplevel() window.
I have made some changes to your code and without having Bio.Blast I have changed some things to what I think you might need to do.
