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 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 รจ 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 need your help in order to solve this problem.
I am trying to enter a line in a database where the program has to find a material X in the database and then get the quantity value. After that, the program creates a new line where it adds the stock entered by the user + the current stock in a new line. The program works as long as the last line in the database is the same material X, but in case the last line is for material Y, then it raises this error.

Happy new year 2021 and thanks for your help
This line causes the error if no records match the selection criteria in the query:
total = lastrecord.fetchone()[0]
If no records match then lastrecord.fetchone() evaluates to None, resulting in the TypeError.
You could handle this by using a try/except block:
try:
total = lastrecord.fetchone()[0]
except TypeError:
total = 0
or an if/else:
row = lastrecord.fetchone()
if row is None:
total = 0
else:
total = row[0]
or more succintly
row = lastrecord.fetchone()
total = row[0] if row is not None else 0
I have defined a function here and it is supposed to work correctly because im using a similar function somewhere else but without giving any conditions(where.. like or regexp) and it works fine there, when i use regexp and all it does not give an output. Why is that? Thanks in advance :)

The syntax of the SELECT statement is incorrect:

should be:
SELECT * from books where `{selected}` regexp '{e_sch.get()}';
Field name should be surrounded by ``, not ''.
I am trying to restore SQL server backup using python. I have a UI built in Tkinter which accepts the filepath and other details like servername, databasename, etc. For testing I am just using localhost. There are two file that I have developed. One called tool.py that has the UI and the other file called Restorebackup.py which has the logic to restore the database. When you run the tool.py file and press the start button it asks you for the file path of the .dat_bak or .bak file that you want to restore. After choosing the .dat_bak file you wait for some time and you get the message as "Backup is restored". I go to SQL Server Management Studio and see the databases in localhost. It shows that backup is restoring with the blue arrow. Unfortunately it never completes and is stuck there forever. When I just run the Restorebackup.py by hardcoding filepath and other values it restores backup perfectly fine. Not sure what is the issue

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)
