    list=["aa","aa","bb","a","dd","ee","ee","f","aa","aa"]
    counts = {}
    for index, key in enumerate(list):
        if key in counts:
            counts[key] += 1
            list[index] = f'{key}_.{counts[key]}'
        else:
            counts[key] = 0

结果

['aa', 'aa_.1', 'bb', 'a', 'dd', 'ee', 'ee_.1', 'f', 'aa_.2', 'aa_.3']
