I need help writing a python code that returns the number of unique elements in a tuple without using the append function or set function. Our assignment recommended that we make a second tuple containing each element only once and having it return the length for the second tuple, but when I try that I$\text{'}$m accidentally excluding the values that appear more than once. I need to include the number of unique values without double counting them. I'll attach a picture of my solution $($trying to create a second tuple$),$ it's not working because it's only counting values that appear once but I need to know the number of elements that appear $($I just should only count them once$).$ The other picture was a suggested solution from someone here, but it doesn't work either because it only counts values that appear once.

I need a solution that counts every element, then I need to remove duplicates. But without using append or set. I can use if$/$elif$/$else or try$/$except$,$ or the count function from an introcs module $($the one I used in my answer$).$ I$\text{'}$m very limited in tools I can use because this is a very basic python class.

Thank you for your time!

Implement

uniques

Read the specification of the function

uniques in the module

Implement this function according to

its specification. As a hint, we suggest

you take the following approach:

make a new tuple that contains each

element of the original tuple, but

only contains it once. Then return the

length of this new tuple.

When you have implemented the

function, test your answer with the

test script. You should now pass all

tests.

Check the Function

You may run this test multiple times.

The call uniques $((5,9,5,7))$

returns $2,$ not $3.$ Implement uniques

The call uniques $((5,9,5,7))$ returns $0,$ not $3.$

def uniques$($tup$)$:

$"""$

Returns the number of unique elements in the tuple.

Examplse:

uniques $((5,9,5,7))$ returns $3$

uniques$((5,5,1,\text{'}$a$\text{'},5,\text{'}$a$\text{'}))$ returns $3$

uniques$(())$ returns $0$

Parameter tup: the tuple to copy

Precondition: tup is a tuple

$""!$

result $=()$

for $x$ in tup:

if introcs.count$\_$tup$($tup$,$x$)==1$:

result $=$ result $,$

sectup $=()$

for $x$ in tup:

if introcs.count$\_$tup$($tup$,$x$)>1$:

sectup $=$ sectup $,$

return len$($result$,)-$len$($sectup$,)$
