{範例}
1. 學生分蘋果
2. 總和及排序
3. 檢查網址格式
4. 以字串排版函式列印成績單
5. 轉換日期格式


```python
#1.
person = int(input("請輸入學生人數: "))

ret = divmod(apple, person)
print("每個學生可分得蘋果 " + str(ret[0]) + " 個")
print("蘋果剩餘 " + str(ret[1]) + " 個")
```

    請輸入學生人數: 5
    請輸入蘋果總數: 24
    每個學生可分得蘋果 4 個
    蘋果剩餘 4 個
    


```python
#2.
innum = 0
list1 = []
while(innum != -1):
    innum = int(input("請輸入電費 (-1：結束)："))
    list1.append(innum)
list1.pop()
print("共輸入 %d 個數" % len(list1))
print("最多電費為：%d" % max(list1))
print("最少電費為：%d" % min(list1))
print("電費總和為：%d" % sum(list1))
print("電費由大到小排序為：{}".format(sorted(list1, reverse=True)))
```

    請輸入電費 (-1：結束)：20
    請輸入電費 (-1：結束)：30
    請輸入電費 (-1：結束)：-1
    共輸入 2 個數
    最多電費為：30
    最少電費為：20
    電費總和為：50
    電費由大到小排序為：[30, 20]
    


```python
