Still stuck, here is what I have so far. I tried putting the entire code into a Try Except - but it still didn't show me the test case that was failing. Passing all the basic tested up to #18

def rank(st=9999, we=9999, n=9999):
try:
print(st,we,n)
st = st.split(',')

    alpha_score = {
        'a':1,
        'b':2,
        'c':3,
        'd':4,
        'e':5,
        'f':6,
        'g':7,
        'h':8,
        'i':9,
        'j':10,
        'k':11,
        'l':12,
        'm':13,
        'n':14,
        'o':15,
        'p':16,
        'q':17,
        'r':18,
        's':19,
        't':20,
        'u':21,
        'v':22,
        'w':23,
        'x':24,
        'y':25,
        'z':26,
    }

    if st == 9999:
        return 'No participants'

    elif st[0].isalpha():
    
    #try:
        if n > len(st):
            return 'Not enough participants'
    
    
        else:
            n = n - 1
            score_list = []
            name_list = []
            sorted_name_list = []
            sorted_score_list = []
            score_name = {}

            for name in st:

                som = 0
                som += len(name)
                for letter in name.lower():
                    som += alpha_score[letter]
                som = som * we.pop(0)
                if som in score_list:
                    name_confirm = []
                    name_confirm.append(score_name[som])
                    name_confirm.append(name)
                    name_confirm.sort()
                    if name_confirm[0] == name:
                        som += .01
                        score_list.append(som)
                        score_name[som] = name
                    else:
                        som -= .01
                        score_list.append(som)
                        score_name[som] = name
                    
                else:
                    score_list.append(som)
                    score_name[som] = name
            
            for k,v in sorted(score_name.items(), reverse=True):
                sorted_score_list.append(k)
                sorted_name_list.append(v)

        return sorted_name_list[n]
#except:
        print(st, we, k)
    
    else:
        return 'No participants'
except IndexError:
    print(st, we, k)

I'm trying to solve this with python and I am getting the following:
STDERR
Traceback (most recent call last):
File "main.py", line 85, in
randomTests()
File "main.py", line 83, in randomTests
Test.assert_equals(rank(st, we, k), rankSol(st, we, k))
File "main.py", line 52, in rankSol
res.append([f[i], we[i] * scoreSol(f[i])])
IndexError: list index out of range

I know list index out of range is usually from calling an out of range index value on a list, like lista = [0, 1, 2] and then I try and run lista[3] but I am not really sure where this could be happening in my code. Any thoughts are appreciated!

Thanks!
