新手小白求助代码问题

题目是：1）Write a program that asks the user their first name, last name,and age. 2）Then, save this information in a dictionary and print their full name plus how many years they have until retirement (65 years old).

我写的代码是：
first_name = input("what is your first name"/n)
what is your first name?
Kristin
print(first_name)
last_name = input("what is your last name"/n)
what is your last name?
Koo
print(last_name)
age = input("How old are you"/n)
How old are you?
print(age)
print("first_name"+"last_name")
remaining = (65-age)
print(remaining)

求教：1）这段代码怎样改才正确？总是显示name error，非常感谢
2）题目中要求将用户的姓，名和年龄存到dictionary里面，这个如何在代码中提现？

# 题目是：1）Write a program that asks the user their first name, last name,and age.

dictionary = {}
first_name = input("what is your first name")# input后面不需要换行符
last_name = input("what is your last name")
dictionary = last_name# 字典形式存储
age = input("How old are you")
print(dictionary)
remaining = (65 - int(age))# input接收的数据是字符串，不能直接运算，要转换为数值
print(first_name + last_name + '，you have ' + str(remaining) + ' years until retirement')# 变量不需要加引号，加了就变成字符串了，不是变量了

first_name = input("what is your first name?")
last_name = input("what is your last name?")
age = int(input("How old are you?"))

name = first_name+last_name
print(name,"'s age is:",age)
print("It's ",65-age," years before retirement")

不好意思，我想问一下，就是这个代码，为啥一开始要弄一个空的dictionary。谢谢🙏

为了后面增加数据啊，你要基础先学完才行啊
如果没有先定义个空字典
就会报错：
Traceback (most recent call last):
File "D:/python/test/test01.py", line 7, in <module>
    dictionary = last_name# 字典形式存储
NameError: name 'dictionary' is not defined

哇！感谢感谢，非常感谢。明白了（我也想先把基础打好，然而教授貌似没从基础开始交，全靠摸索{:10_277:}

教授？你还在上学的么？
看看甲鱼的视频，或者哔哩哔哩上搜下黑马程序员，也会有基础的视频讲解，先学完基础，否则瞎子摸象，全靠猜了
