You can't re-use the cursor.
Declare a local cursor each time:
# Get a Record in DB
def get_valid_guessing_word(self, id):
cursor = self.con.cursor() # <<-- HERE new cursor
cursor.execute("SELECT * FROM DICTIONARY WHERE id=?", (id,))
valid_word = cursor.fetchone()
print(valid_word)
return valid_word
As #kuro has pointed out in multiple comments, at no time does the Database.add_valid_guessing_word() function get called in the code. So the table is empty, so the call to db.get_valid_guessing_word(random.randint(1, 7)) returns None. This is not a list-type, hence the error.
Modify your code to put the Animals into the database:
window.title("Hangman")
db = Database("Goiyala.db")
db.add_valid_guessing_word() # <<-- HERE Populate the database
But this will continually add the words, so perhaps check to see if it's not empty first, something like:
window.title("Hangman")
db = Database("Goiyala.db")
if ( db.get_valid_guessing_word( 0 ) == None ):
db.add_valid_guessing_word() # <<-- HERE Populate IFF empty
Then you can also do a debug-dump of the database:
class Database:
# ...
def dumpAnimals( self ):
""" Debug function to dump the Animal Dictionary Table """
cursor = self.con.cursor()
cursor.execute( "SELECT id, word FROM Dictionary ORDER BY word" )
for row in cursor.fetchall():
if ( row == None ):
print( "Dictionary Table is empty" )
break
else:
id_num, word = row
print( "id=%3d, word=[%s]" % ( id_num, word ) )
Using this like:
window.title("Hangman")
db = Database("Goiyala.db")
if ( db.get_valid_guessing_word( 0 ) == None ):
db.add_valid_guessing_word() # <<-- HERE Populate IFF empty
db.dumpAnimals() # <<-- HERE Check we have data

Code below will do the trick perfectly (just adjust it to your needs):
import tkinter as tk
def safe_to_sql(number):
print("Saving room {} into SQL ...".format(number))
#Save whatever you want
def addButton(window, buttons, room):
new_button = tk.Button(window, text = "Room:" + room, command = lambda: safe_to_sql(room))
new_button.pack()
buttons.append(new_button)
my_buttons = []
rooms = ["Room 1", "Super room 2", "Ever better one"]
window = tk.Tk()
for room in rooms:
addButton(window, my_buttons, room)
window.mainloop()
We are creating dynamical buttons.
To each button we connect this lambda function: command = lambda: safe_to_sql(room).
I am a beginner in coding and this new community.I need your help to understand why it is not possible to get this solution. I would like to get a number from an entry and then sum up with the last record of the same item, so I can aggregate it.

time = datetime.now().strftime("%B %d, %Y")
hour = datetime.now().strftime("%I:%M%p")
query = 'SELECT totalstock FROM stocks WHERE name = ? AND MovementID = ( SELECT max( MovementID ) FROM stocks)'
parameters = (self.name.get(),)
lastrecord = self.run_query(query, parameters)
total = lastrecord + self.quantity.get()
if self.validation():
query = 'INSERT INTO stocks VALUES(NULL, ?, ?, ?, ?, ?)'
parameters = (self.name.get(), self.quantity.get(), total, time, hour)
self.run_query(query, parameters)
self.message['text'] = 'Movement {} added succesfully'.format(self.name.get())
self.name.delete(0, END)

Thanks in advance and kind regards.
The exception is raised on line 72 of your code. The code attempts to add a string object to a sqlite.Cursor object, which fails because these types are incompatible for that operation.
Instead you need to extract the data held in the returned Cursor object which can be done like this:
total = lastrecord.fetchone()[0]
fetchone() returns the first row of the data which is of type tuple. The first item in the tuple is the queried value, which is assumed to be an integer in this case. You can't add the string returned by self.quantity.get(), so you need to convert that to an integer (assuming that it is an integer.. it could be another numeric type) to calculate the new total:
total += int(self.quantity.get())
I'm trying to save new data in sqlite and get an error.
Code:
def saveChanges(player_to_save, player_id):
db = sqlite3.connect('db_player.db')
sql = db.cursor()
sql.execute(f"""UPDATE users SET (lvl = {player_to_save.lvl}, exp = {player_to_save.exp}, hp = {player_to_save.hp}, items = {converToJson_items(player_to_save)}, weapon = {convertToJson_weapon(player_to_save)}, armour = {convertToJson_armour(player_to_save)}, bounus = {convertToJson_bounus(player_to_save)}, bonuses_award = {convertToJson_bonuses_award(player_to_save)}, stats = {converToJson_stats(player_to_save)} ) WHERE login = '{player_id}'""")

sqlite3.OperationalError: near "=": syntax error
How can i fix it?
Use this syntax-
sql.execute('''UPDATE tablename SET v1 = ?, v2 = ? where c1 = ?;''', (new_val1, new_val2, condition))
I have a table that has only 1 row, I only need to update the data in the first row. I need to preview the data at the startup like Total Wealth :- 2000 Cash :- 0 Savings :- 2000. But it previews like shown below. enter image description here So please give me a solution for this.

cursor.execute("commit;")
if (connection):
cursor.close()

t_w_lbl.place(rely=0.04, relx=0.1)
cash_lbl = Label(text="Cash = " + str(cash), font=("Calibry", 14), bg="white")
cash_lbl.place(rely=0.04, relx=0.45)
photo = PhotoImage(file = "exchange.png")
exchange_btn = Button(image = photo, command = lambda: exchange())
exchange_btn.place(relx = 0.64, rely = 0.03, height = 35, width = 50)
savings_lbl = Label(text="Savings = " + str(savings), font=("Calibry", 14), bg="white")
savings_lbl.place(rely=0.04, relx=0.8)`
You should use the fetchone method instead and unpack the returning tuple (note the added comma).
Change:
cash = cursor.fetchall()
...
savings = cursor.fetchall()
to:
cash, = cursor.fetchone()
...
savings, = cursor.fetchone()
