Changing the letters in a string to upper case and lower case before an inputted letter

I have a question that I have almost figured out but am stuck on one aspect of it. The question asks me to create a function that takes a letter as a parameter that scans a list of capitals and returns a list of those capitals containing that letter. But it also turns the capital all lower case and makes the letter before and after the parameter letter uppercase. I have been able to figure out how to do it when there is only a single letter but in the case of the capital brazzaville where the parameter letter is 'z' I am struggling to get it to return it as brAzzAville. Ican only get it to return brAzZaville.

This is the code that I have so far:

    def get_funny_case_capital_cities(letter):
        my_list = []
        for element in capitals:
            if letter.lower() in element.lower():
               capital_city = list(element.lower())
               capital_city.append("")
               for i, name in enumerate(capital_city):
                       if name == letter:
                               capital_city[i] = capital_city[i].lower()
                               capital_city[i-1] = (capital_city[i-1].upper())
                               capital_city[i+1] = (capital_city[i+1].upper())
                capital_city.pop()
                capital_city = "".join(capital_city)
    my_list.append(capital_city)
return my_list


    print(get_funny_case_capital_cities('z'))

this gives me an output of: ['brAzZaville', 'zAgreb', 'vadUz']

capitals is a list of all country capitals in the world.

     capitals = (
'Kabul', 'Tirana (Tirane)', 'Algiers', 'Andorra la Vella', 'Luanda', "Saint John's", 'Buenos Aires', 'Yerevan',

I am stuck on getting it too skip the second repeated letter.

Thanks for the help!

You need to walk through this logic, perhaps using pencil & paper:

            capital_city[i] = capital_city[i].lower()
            capital_city[i-1] = (capital_city[i-1].upper())
            capital_city[i+1] = (capital_city[i+1].upper())

Note the trailing upper call in this trio: you capitalize position i-1, even if you've already determined that it must be lower case in the previous iteration.

Instead, just check to see whether it's the target letter:

            capital_city[i] = capital_city[i].lower()
            if i > 0 and capital_city[i-1] != letter:
                capital_city[i-1] = (capital_city[i-1].upper())
            if if i < len(capital_city)-1 and capital_city[i+1] != letter:
                capital_city[i+1] = (capital_city[i+1].upper())
