## 自我介紹
高三 沒有程式基礎 從0開始學
原先希望自己參加這個營隊後可以對程式有基礎認識，目的地有達到。
有學到一些不錯的程式。

## 感想心得
雖然高中課程有上一點程式，但是大多沒在聽或是有聽沒有懂，利用這次機會我重新認識了一次python的基礎。滿有收穫的。

## 有趣程式
```python=
**n=int(input())

if n<=10:
    print(n6)
elif 11<=n<=20:
    print(60+(n-10)2)
elif 21<=n<=40:
    print(80+(n-20)1)
elif 41<=n:
    print(100)*
```
這題滿簡單的
