### {綜合演練}
實作2
輸入喜歡的水果，直到Enter鍵結束，找尋fruit = ["香蕉","蘋果","橘子","鳳梨","西瓜"]水果串列是否包含此水果，並顯示該水果是串列中的第幾項
```python
list1 = []
list2 = ["櫻桃", "葡萄", "楊桃"]
list3 = [["捷克", "印度","芬蘭"], ["游泳", "籃球", "保齡球"]]
print(list1)
print(list2)
print(list3)
```
```python
print("我最想去旅遊的地方 %s" % list3[0][0])
```
我最想去旅遊的地方 捷克
```python
print(list2[0:2:1])
```
['櫻桃', '葡萄']
```python
list2.append("香蕉")
print(list2)
```
['櫻桃', '葡萄', '楊桃', '香蕉']
```python
list2.pop()
```
'楊桃'
pop可以不寫參數，就是把最後一個除掉
```python
print(list2)
```
['櫻桃', '西瓜']
```python
list2[1] = "西瓜"
print(list2)
```
['櫻桃', '西瓜']
```python
list2.insert(0,"西瓜")
print(list2)
```
['西瓜', '櫻桃', '櫻桃', '櫻桃']
```python
list2.remove('西瓜')
```
```python
print(list2)
```
['櫻桃', '櫻桃', '櫻桃']
```python
list2.sort()
print(list2)
list2.reverse()
print(list2)
print(max(list2))
```
['櫻桃', '櫻桃', '櫻桃']
['櫻桃', '櫻桃', '櫻桃']
櫻桃
### {範例}
1. 串列出值設定 \<list1>
2. 使用 for 迴圈讀取串列元素 \<list2>
3. 利用迴圈配合索引讀取串列元素 \<list3>
4. 以串列計算班級成績 \<append1>
5. 刪除指定串列元素 \<remove>
6. 成績由大到小排序 \<sorted>
```python
list4 = [100, 89, 79]
print(max(list4))
print(min(list4))
print(len(list4))
print(list4.count(79))
print(list4.index(100))
```
100
79
3
1
0
數列中，第一個數字的index為0
```python
#使用 for 迴圈讀取串列元素 <list2>
print(list4)
for n in list4 :
print(n, end = ' ')
```
[100, 89, 79]
100 89 79
```python
for i in range(len(list4)) :
print(i, list4[i], sep= ",")
```
0,100
1,89
2,79
```python
list2 = ["櫻桃", "葡萄", "楊桃"]
for i in range(len(list2)) :
print(i, list2, sep= ",")
```
0,['櫻桃', '葡萄', '楊桃']
1,['櫻桃', '葡萄', '楊桃']
2,['櫻桃', '葡萄', '楊桃']
```python
#以串列計算班級成績 <append1>
score = [100, 90, 50, 70, 100, 100, 60, 30, 70, 80]
ttl = 0
avg = 0
n = 0
for score in score :
ttl = ttl + score
n = n + 1
avg = ttl / n
print("總成績 : %3.0f , 平均成績 : %0.2f" % (ttl, avg))
```
總成績 : 750 , 平均成績 : 75.00
```python
score = []
inscore = 0
ttl = 0
avg = 0
while inscore !=-1 :
inscore = int(input("enter your score , to end just enter -1 and enter"))
if inscore != -1 :
score.append(inscore)
n = 0
for n in range(len(score)) :
ttl = ttl + score[n]
avg = ttl / n
print("共有%d人" "總成績 : %3.0f" "平均成績 : %0.2f" % (n, ttl, avg))
```
enter your score , to end just enter -1 and enter100
enter your score , to end just enter -1 and enter90
enter your score , to end just enter -1 and enter80
enter your score , to end just enter -1 and enter70
enter your score , to end just enter -1 and enter60
enter your score , to end just enter -1 and enter100
enter your score , to end just enter -1 and enter-1
共有5人總成績 : 500平均成績 : 100.00
當要相加的時候，要用range把數列的位置表示出來
for迴圈不用再n = n + 1
```python
#刪除指定串列元素 <remove>
fruits = ["櫻桃","葡萄","楊桃","香蕉","酪梨","西瓜","龍眼"]
to_del = "西瓜"
fruits.pop(5)
print(fruits)
```
['櫻桃', '葡萄', '楊桃', '香蕉', '酪梨', '龍眼']
pop可以刪除列陣中的元素

西元2021年是牛年。請你開發一個程式:
當使用者輸入他的出生西元年之後，畫面會顯示這個西元年的生肖。
