Not getting the correct result for my output in average function

I've been working on do loops for python although there isn't one for the language. I am trying to get the average of certain integers entered until a negative integer is entered. I was able to get the program working, instead it gives me the wrong results after entering the numbers and getting the average. For instance, if I provide a set of 5 numbers, and then enter a negative number to calculate it, it gives me an answer of 1.0. I would like some advice on how to get rid of this issue to get the accurate answers for finding the average from the 5 set of numbers entered.

Will process and calculate the average totalScore = 0 getTestScore: int = 0 total = getTestScore + 1 count = getTestScore count: int = count + 1 totalScore = getTestScore() averageTestScore = float(totalScore) / count

return averageTestScore

    # Do loop function
    total = 0
    count = 0
    totalTestScore = total + 1
    average = calculateAverage(totalTestScore, count)
    while True:    #This simulates a Do Loop
        testScore = getTestScore()
        totalTestScore = total + 1
        count = count + 1
        if not(testScore >= 0): break   #Exit loop
    calculateAverage(totalTestScore, count)
    
    return average

I'm unsure of where I went wrong to get the same answer, 1.0 for every different number I enter.

I tried changing around the positions of where they were on the line and how they were indented to make sure it was corrects. The program plan I wrote is very simple and I'm trying not to drastically change it to not match my program plan.

def average(x):
    total = 0
    count = 0
    for i in x:
        count += 1
        total += i
    return total/count
        

lst = []
num_input = int(input("enter the numbers"))
while num_input >= 0:  # This simulates a Do Loop
    lst.append(num_input)
    num_input = int(input("enter the numbers"))   
#print(lst) 

average(lst)
