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 = Tk()
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.

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}"

Why i need this comanda user = dict()? I am telling the programn that the variable user is a dict() and thats ok, but i want to know if put user = {} would do same harm to the code
The statement user = dict() creates a new and empty python dictionary which you then fill with content on the subsequent line.
The approach looks rather non-pythonic to me. I would rather initialize and fill the dictionary in one go as TheLizzard suggested:
user = {"name": e_name.get(), "last__name": e_lastname.get(), ...}
You can achieve the same thing with the dict() method but it may result in more visual clutter in this case. However, the dict() method comes with a bunch of other handy ways to create and fill dictionaries in programmatic ways. e.g. this resource gives a nice overview: https://www.programiz.com/python-programming/dictionary
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 :)

c.execute(f"SELECT * from books where '{selected}' regexp
'{e_sch.get()}';")
result = c.fetchall()

num = 0

lookup_label = Label(result_win, text=y)

Sometimes i get this error too UnboundLocalError: local variable 'index' referenced before assignment
The syntax of the SELECT statement is incorrect:
SELECT * from books where '{selected}' regexp '{e_sch.get()}';
should be:
SELECT * from books where `{selected}` regexp '{e_sch.get()}';
Field name should be surrounded by ``, not ''.

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)
I'm still working on my quiz program but I'm currently having an issue with getting the program to increment the questions which are retrieved from a database that I also have. When I try to move to the next record in my database I haven't been able to actually change the contents of the page, everything stays as it is and I have to this point not been able to rectify the issue. I feel as though it's an issue with my use of variable but I cant think of any way around this. Here's the section of my code where I'm having this issue:

I'm not sure how else i could go about trying to get the contents of the page to change but i hope i can learn from someone else here as nobody around me is very helpful at all (including teachers) and this is the best option I have. Thanks in advance for any help.
I can't test it but I would do something like in code.
In __init__ I create empty labels and execute separated method which reads data from database and puts them in labels. later I can use this method to get next question.
To get one row from database you can use fetchone(). To get data from row you don't have to use str() and strip() but index row[0], row[1], etc. You may have to change indexes if you have columns in different order in database.
