Character Repeater Function

I need to create a function in Python to iterate over a given string, in this case 'hello-world' and have an output where characters in the string that do not have pairs, are printed with a paired character.

Input String: hello-world

Output String: hheello--wworrldd

So for this example, I only want to repeat the characters 'h' 'e' 'w' 'r' 'd' and not repeat 'l' or 'o' I tried this function, and it did repeat the characters, but I am not sure how to isolate only the characters that do not have a pair in the string.

def character_pair(n, input_string):
    word = ''
    for char in list(input_string):
        word += char * n
    print (word)

character_pair(2, 'hello-world')

This was my output: hheelllloo--wwoorrlldd

def repeatChar(n, sentence): 
    words = ''
    for char in list(sentence):
        word += char * n
    print(words)


sentence = input('Here you can write.. ')
repeatChar(2, sentence)

string = 'hello-world'
new_word = ''

for each_char in string:
    if string.count(each_char) > 1:
        new_word += each_char
    else:
        new_word += each_char * 2

Use collections.Counter to count the repetitions of each character. Then check if the count is 1 before multiplying the character.

import collections

def character_pair(n, input_string):
    counts = collections.Counter(input_string)
    word = ''
    for char in input_string:
        if counts[char] > 1:
            word += char
        else:
            word += char * n
    print (word)

character_pair(2, 'hello-world')
