I am making a small app with Tkinter, for educational purposes, which consists of pressing a button and displaying the contents of a textobox ... in another multiline textbox.
The problem is that you see this:
<bound method Text.get of <tkinter.Text object.! Text2 >>
and not the content that I manually write of the textobox. The textbox that I would like to print in the multiline textobox (called text) is called textbox_test. Textbox_test is called
A = f "{test_textbox.get} {'' .join (word2)} {abitanti} abitanti su un'area di {superficie}".
Questo è il textobox
test_textbox = Text(window,width=10,height=1)
test_textbox.pack()
test_textbox.place(x=5, y=100)
How can I remove the error above and correctly display the text of a textbox? I attach complete code. Thank you

IMPORTANT: If you try to change to A = f "{test_textbox.get (" 1.0 "," end-1c ")} {'' .join (word2)}, that's not good. The app won't open. Without this code instead opens
As #BryanOakley said in comment you need get with () to run it and widget Text needs it with arguments like
A = f"{test_textbox.get('1.0','end-1c')} ...
It didn't work because it was only part which you would have to replace in full text, but it seems you replaced all text. Because you didn't run code in console so you couldn't see error message which could explain problem
Full line should be
A = f"{test_textbox.get('1.0','end-1c')} {''.join(word2)} {inhabitants} inhabitants on an area of {surface}"

I am trying to make a weather forecast "app" using python, following the instructions of this video: https://www.youtube.com/watch?v=7JoMTQgdxg0
Everything works fine, except from the functionality of displaying some icons to make it look better.
If i remove the code that its used for the icons, everything works perfect. I don´t know what I should do so this works.
from tkinter import *
from tkinter import messagebox
from configparser import ConfigParser
import requests
url = "https://api.openweathermap.org/data/2.5/weather?q={}&appid={}"
config_file = 'config.ini'
config = ConfigParser()
config.read(config_file)
api_key = config['api_key']['key']
def get_weather(city):
result = requests.get(url.format(city, api_key))
if result:
#print(result.content)
json = result.json()
#City, country, temp_celsius, temp:farenheit, icon weather
city = json['name']
country = json['sys']['country']
temp_kelvin = json['main']['temp']
temp_celsius = temp_kelvin - 273.15
temp_farenheit = (temp_kelvin - 273.15) * 9 / 5 + 32
icon = json['weather'][0]['icon']
weather = json['weather'][0]['main']
final = (city, country, temp_celsius, temp_farenheit, icon, weather)
return final
else:
return None
#print(get_weather('London'))
def search():
city = city_text.get()
weather = get_weather(city)
if weather:
location_lbl['text'] = '{}, {}'.format(weather[0], weather[1])
image['bitmap'] = 'weather_icons/{}.png'.format(weather[4])#HERE ITS THE PROBLEM
temp_lbl['text'] = '{:.2f}ºC, {:.2f}ºF'.format(weather[2], weather[3])
weather_lbl['text'] = weather[5]
else:
messagebox.showerror('Error', 'Cannot find city {}'.format(city))
app = Tk()
app.title("Weather App")
app.geometry('700x350')
city_text = StringVar()
city_entry = Entry(app, textvariable=city_text)
city_entry.pack()
search_btn = Button(app, text='Search Weather', width=12, command=search)
search_btn.pack()
location_lbl = Label(app, text="", font=('bold', 20))
location_lbl.pack()
image = Label(app, bitmap='')#HERE ITS THE PROBLEM
image.pack()
temp_lbl = Label(app, text="")
temp_lbl.pack()

I also have another file that its called: config.ini for saving my API key, and a folder named weather_icons for storing the images

I'm unable to update my table in MySQL using Tkinter. It just won't get updated. I have tried checking where the table name is different but it's not. It shows no errors but not getting updated.
from tkinter import *
t = Tk()
t.geometry("500x500")
Label(text = 'Name:').place(x=10,y=10)
nm = Entry()
nm.place(x=55,y=12)
Label(text = 'age:').place(x=10,y=35)
ag = Entry()
ag.place(x=55,y=37)
def abcd():
import pymysql
x = pymysql.connect(host = 'localhost',user = 'root',password = 'admin',db ='db')
cur = x.cursor()
n= nm.get()
a = ag.get()
cur.execute('insert into sample2 values(%s, %s)',(n,a))
x.commit()
x.close()
Button(text ='Submit',command = abcd).place(x=40,y=65)
Label(text ='UPDATE',fg = 'white',bg = 'black',font = ('Times new roman',24,'bold')).place(x=10,y=100)
Label(text ='Enter the name to update').place(x = 5,y = 155)
b=Entry()
b.place(x = 150, y = 157)
Label(text = 'Enter new age:').place(x=5,y = 200)
nag = Entry()
nag.place(x=150,y = 202)
'''print(b)'''
def upd():
import pymysql
x = pymysql.connect(host = 'localhost',user = 'root',password = 'admin',db ='db')
cur = x.cursor()
gnd =b.get()
anag = nag.get()
cur.execute('update sample2 set age =%s where name = %s',(gnd,anag))
x.commit()
x.close()
t.mainloop()
Button(text = 'apply',command = upd).place(x = 200, y = 300)
t.mainloop()
It is because the order of the arguments used in UPDATE is wrong:
cur.execute('update sample2 set age =%s where name = %s',(gnd,anag)) # wrong order of arguments
So the WHERE clause is evaluated as False and no record will be updated.
It should be:
cur.execute('update sample2 set age =%s where name = %s',(anag, gnd))
I am writing a simple app to calculate some values according to entered value by user. I almost accomplished it!
Now I want to know:
1. How can I clear my txtFixedIncome text box every time I click on it?
2. How can it be implemented to display the content of txtFixedIncome text box with thousands separator (digit group separator)? i.e. displaying 27659 as 27,659.
import tkinter
mainForm = tkinter.Tk()
mainForm.title('Shahr Fixed Income Fund')
def btnCalculatePressed():
txtCalculationResult.delete('1.0', 'end')
#txtCalculationResult.insert(tkinter.INSERT, "Button was pressed")
#txtCalculationResult.pack()
yourIncomePortion = txtFixedIncome.get('1.0', 'end')
print(yourIncomePortion)
txtCalculationResult.insert(tkinter.INSERT, yourIncomePortion)
btnCalculate = tkinter.Button(mainForm , text = "Calculate", command= btnCalculatePressed)
txtCalculationResult = tkinter.Text(mainForm )
txtCalculationResult.insert(tkinter.INSERT, "CalculationResults")
txtFixedIncome = tkinter.Text(mainForm, height = 1, width = 30 )
txtFixedIncome.insert(tkinter.INSERT, "your income portion")
txtFixedIncome.pack();
txtCalculationResult.pack()
btnCalculate.pack()
mainForm.mainloop()
Solution of first question:
bind focus in and focus out of your widget. Like:
txtFixedIncome.bind("<FocusIn>",lambda _:txtFixedIncome.delete('1.0', 'end'))
txtFixedIncome.bind("<FocusOut>",lambda _:txtFixedIncome.insert("1.0","your income portion" if str(txtFixedIncome.get("1.0","end")) == "\n" else ""))
This will erase all data in entry when focused out and enter information data when focused in.
Solution of second question:
You can make a function to update your values and format them like:
def updat(text):
try:txtCalculationResult.insert(tkinter.INSERT,"{:,.0f}".format(float(text)))
except:txtCalculationResult.insert(tkinter.INSERT,"CalculationResults")
As:
>>> "{:,.0f}".format(23442)
'23,442'
>>>
Full code:
Here is a full example code that shows the behavior you are expecting:
import tkinter
mainForm = tkinter.Tk()
mainForm.title('Shahr Fixed Income Fund')
def updat(text):
try:txtCalculationResult.insert(tkinter.INSERT,"{:,.0f}".format(float(text)))
except:txtCalculationResult.insert(tkinter.INSERT,"CalculationResults")
def btnCalculatePressed():
txtCalculationResult.delete('1.0', 'end')
yourIncomePortion = txtFixedIncome.get('1.0', 'end')
updat(yourIncomePortion)
btnCalculate = tkinter.Button(mainForm , text = "Calculate", command= btnCalculatePressed)
txtCalculationResult = tkinter.Text(mainForm)
txtCalculationResult.insert(tkinter.INSERT, "CalculationResults")
txtFixedIncome = tkinter.Text(mainForm, height = 1, width = 30 )
txtFixedIncome.insert(tkinter.INSERT, "your income portion")
txtFixedIncome.bind("<FocusIn>",lambda _:txtFixedIncome.delete('1.0', 'end'))
txtFixedIncome.bind("<FocusOut>",lambda _:txtFixedIncome.insert("1.0","your income portion" if str(txtFixedIncome.get("1.0","end")) == "\n" else ""))
txtFixedIncome.pack();
txtCalculationResult.pack()
btnCalculate.pack()
mainForm.mainloop()
Format during typing:
If you want to format the string during typing as you commented then use the following code:
import tkinter
mainForm = tkinter.Tk()
mainForm.title('Shahr Fixed Income Fund')
def updat(text):
try:txtCalculationResult.insert(tkinter.INSERT,"{:,.0f}".format(float(text.replace(",",""))))
except:txtCalculationResult.insert(tkinter.INSERT,"CalculationResults")
def btnCalculatePressed():
txtCalculationResult.delete('1.0', 'end')
yourIncomePortion = txtFixedIncome.get('1.0', 'end')
updat(yourIncomePortion)
btnCalculate = tkinter.Button(mainForm , text = "Calculate", command= btnCalculatePressed)
txtCalculationResult = tkinter.Text(mainForm)
txtCalculationResult.insert(tkinter.INSERT, "CalculationResults")
txtFixedIncome = tkinter.Text(mainForm, height = 1, width = 30 )
txtFixedIncome.insert(tkinter.INSERT, "your income portion")
def updat2():
text = txtFixedIncome.get("1.0","end")
txtFixedIncome.delete("1.0","end")
try:
txtFixedIncome.insert(tkinter.INSERT,"{:,.0f}".format(float(text.replace(",",""))))
except:
txtFixedIncome.insert(tkinter.INSERT,text[:-1])
txtFixedIncome.bind("<FocusIn>",lambda _:txtFixedIncome.delete('1.0', 'end'))
txtFixedIncome.bind("<FocusOut>",lambda _:txtFixedIncome.insert("1.0","your income portion" if str(txtFixedIncome.get("1.0","end")) == "\n" else ""))
txtFixedIncome.bind("<Key>",lambda _:mainForm.after(50,updat2))
txtFixedIncome.pack();
txtCalculationResult.pack()
btnCalculate.pack()
mainForm.mainloop()

On line 37 it says NewPage is not defined but I defined it on line 24, please help. this program is object oriented and im a student trying to complete this for my A-Level project. I dont understand alot of this code but any help would be much appreciated. Im a amateur when it comes to python/tkinter/sqlite but need this help otherwise I will fail my course because my teacher is not much help when it comes to programming
You are missing self in your function def NewPage(self): and go to the line which you have root.after(2000, NewPage) and replace it with root.after(2000, self.NewPage)
At first I thought this would be an easy program where I could learn a lot. But I'm stuck.
How can I ask diffrent questions all after eachother. I have tried some things I came up with but none of those work.
This is the first one, where I use a variable x to re-generate the question. This simply doesn't work.
# Laad de database
cnx = mysql.connector.connect(user='FransSchool', password='RandomPass',host='10.0.0.25', database='Overhoor')
cursor = cnx.cursor()
# Maak een grafische interface
gui = Tk()
gui.resizable(width=FALSE, height=FALSE)
# Verklaringen
def verify():
overify = antwoord.get()
if overify == Nederlandsevertaling:
oentry.delete(0,END)
x=0
else:
oentry.delete(0,END)
x = 0
antwoord = StringVar()
willekeurig = random.randint(0,9)
# Indexeer de database
query = "SELECT FRwoord, NLwoord FROM unite8app1 WHERE id=%s"
cursor.execute(query, (willekeurig,))
while x < 1:
for (FRwoord, NLwoord) in cursor:
Fransevertaling = FRwoord
Nederlandsevertaling = NLwoord
x+=1
And this is the second one which gave me an error. It didn't really came as a surprise that this one didn't work. On button press it tries to recieve a new FR and NLwoord.
# Laad de database
cnx = mysql.connector.connect(user='FransSchool', password='RandomPass', host='10.0.0.25', database='Overhoor')
cursor = cnx.cursor()
# Maak een grafische interface

gui.resizable(width=FALSE, height=FALSE)
# Verklaringen
def verify():
overify = antwoord.get()
if overify == Nederlandsevertaling:
oentry.delete(0,END)
willekeurig = random.randint(0,9)
for (FRwoord, NLwoord) in cursor:
Fransevertaling = FRwoord
Nederlandsevertaling = NLwoord
else:
oentry.delete(0,END)
#Save the wrong answer aswell as the right answer to print out at the end
antwoord = StringVar()
willekeurig = random.randint(0,9)
# Indexeer de database
query = "SELECT FRwoord, NLwoord FROM unite8app1 WHERE id=%s"
cursor.execute(query, (willekeurig,))
for (FRwoord, NLwoord) in cursor:
Fransevertaling = FRwoord
Nederlandsevertaling = NLwoord
# Uiterlijk van het venster
gui.configure(background="white")
gui.title("Overhoorprogramma - Bryan")
# Grafische objecten
style = ttk.Style()
olabel = ttk.Label(gui,text=Fransevertaling,font=("Times", 18), background="white")
olabel.grid(row=0, column=0,padx=5, pady=5, sticky="W")
oentry = ttk.Entry(gui,textvariable=antwoord, font=("Times", 18))
oentry.grid(row=1, column=0,padx=5, pady=5)
obutton = ttk.Button(gui,text="Suivant", command = verify)
obutton.grid(row=1, column=1,padx=5, pady=5)
At the moment it just clears the entry box on button press. The goal is that everytime an answer has been typed in right it should skip that and if it is typed wrong it has to save it. Either way it has to create a new question what means a new Frword and NLword.
Ideally I am looking for a push in the right direction, the mechanism behind it or a small snippet of code.
