You are returning a tuple here:

elif retailer_pk:
    return (request, 'page-retailer-single.html', {
        "products": products,
        "sorting": filt["sorting"],
        "filtering": filt["filtering"],
        "retailer": retailer,
    })

Did you forget to add render there perhaps:

elif retailer_pk:
    return render(request, 'page-retailer-single.html', {
        "products": products,
        "sorting": filt["sorting"],
        "filtering": filt["filtering"],
        "retailer": retailer,
    })

Are you initializing guessed_num as a tuple verses an empty list? See the difference in the ipython session below: ```python In [43]: guessed_num = () # declared as a tuple In [44]: guessed_num.append(4) # this will fail AttributeError Traceback (most recent call last) in () ----> 1 guessed_num.append(4) AttributeError: 'tuple' object has no attribute 'append' In [45]: guessed_num = [] # declared as a list In [46]: guessed_num.append(4) # append at will! In [47]: guessed_num Out[47]: [4] ```

items() is a method specifically for dictionaries, not tuples. Tuples are like lists, except they are immutable.

This error indicates that value is a tuple, and not a string as you might expect. This indicates a problem with your application.

Here the problem is that fetchone() returns a one-tuple. You should change from this line:

value = results.fetchone()

to this (notice the comma after value):

value, = results.fetchone()

or this (not recommended):

value = results.fetchone()[0]

---

But why is fetchone() returning a tuple instead of a string? Because you can SELECT multiple columns. Consider for example the following SQL statement:

SELECT a, b, c FROM my_table;

In this case, fetchone() will return a three-tuple.

Writing value, = fetchone() you are telling Python that you are expecting a one-tuple and you want that single item placed into value. If you were expecting the three-tuple, you'd have used column_a, column_b, column_c = resulsts.fetchone().

This is the reason why you should prefer value, over fetchone()[0].

Bonus tip: I noticed you are using Python 3. In this case, you can write:

translation_table = dict.fromkeys(b'+-(),', None)

Speeding up your code and making it more clean.

p1=(input("Name: "),input("Age: "))

As of right now, you're making a 2-tuple, not a Person. This should be

p1 = Person(input("Name: "), input("Age: "))
