In the code below the entry widgets that I use the get method to retrieve data from, have been created earlier in the code.
I have tried the following ways to solve the problem:
turning the list into a tuple
using a list literal
inserting data as variables into the database rather than as a list
getting the data from entry widgets inserting it into python variables, then I inserted the python variables into a list variable and then tried to insert this list variable into the sql database I created
# declares and defines function that checks that data in the 'Password' and ' Confirm Password' entries match
def MatchingPasswordsValidator(): if str(PasswordEntry.get())!= str(ConfirmPasswordEntry.get()): tkinter.messagebox.showerror("","Please ensure the passwords you enter match") else: # declares list variable UserDetails = 
# populates list variable
# inserts user's details into the program's database
c.executemany("INSERT INTO tblUserDetails VALUES(?,?,?,?)",UserDetails)
# saves changes made to database
File "C:\Users\User\Documents\School\CS\Project\Screen2.py", line 135, in MatchingPasswordsValidator c.executemany("INSERT INTO tblUserDetails VALUES(?,?,?,?)",UserDetails) sqlite3.ProgrammingError: Incorrect number of bindings supplied. The current statement uses 4, and there are 1 supplied.
