What you need is a way to scan a famous_city, removing the letters in vowls and print the result as a string:

vowls = ["a", "e", "i", "o", "u"]

famous_cities = ["Muqadishou", "Dubai", "Oslo", "Nairopi"]

for city in famous_cities:
    new_capitol_charlist = []
    # For each character in city
    for char in city:
        # if the lower case version is not in vowls list
        if char.lower() not in vowls:
            # append to new_city_charlist
            new_capitol_charlist.append(char)
    # join new_capitol_charlist into string and print
    print(''.join(new_capitol_list))

# The above can be accomplished in a using a list comprehension
for city in famous_cities:
    new_capitol = ''.join([char for char in item if char.lower() not in vowls])
    print(new_capitol)

There is no .remove method for strings. You can use .replace to remove a letter from a string. Example: newstr = oldstr.replace("M", ""). This would replace M's with "", or nothing.
