I need help writing a python code that returns the number of unique elements in a tuple without using the append or set function built in to python. Our assignment recommended that we make a second tuple only containing eash element once and return th length of that for our answer, but I don't know how to get the new tuple to only contain things once. I thought I might make a tuple with all the elements and subtract the ones that are duplicates, but that make me realize I$\text{'}$m deleting all the doubles instead of keeping one of each element. Here's the coding I have so far. The introcs module is online, I$\text{'}$m very limited it what functions I can use beyond if$/$then$,$ try$/$except$,$ and what's in the introcs module.

Thank you for your time! Here is my work so far:

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 $+($x$,)$

sectup $=()$

for x in tup:

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

sectup $=$ sectup $+($x$,)$

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

Read the specification of the function uniques in the module

funcs $.$ 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 $0,$ not $3.$

def uniques$($tup$)$:

$"""!$

Returns the number of unique elements in the tuple.

Examplse:

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

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

uniques$(())$ returns $0$
