# wk07_1019_串列與元組
<pre>
5.1 串列的使用
5.2 使用for迴圈讀取串列
5.3 串列搜尋與計次
5.4 串列元素新增與刪除
5.5 串列排序
5.6 串列常用的方法列表
5.7 元組(Tuple)
<pre/>
### {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>
## 【inclass practice】
```python
#4 以串列計算班級成績 <append>
scores = [100, 90, 50, 70, 100, 100, 90, 90, 60, 30]
```
```python
scores = []
inscore = 0
while inscore != -1 :
inscore = int(input("enter score, to end just enter -1 and enter "))
if inscore != -1 :
scores.append(inscore)
print(scores)
```
enter score, to end just enter -1 and enter 89
enter score, to end just enter -1 and enter 18
enter score, to end just enter -1 and enter 45
enter score, to end just enter -1 and enter 68
enter score, to end just enter -1 and enter -1
[89, 18, 45, 68]
```python
scores = []
inscore = 0
while inscore != -1 :
inscore = int(input("enter score, to end just enter -1 and enter : "))
if inscore != -1 :
scores.append(inscore)
ttl = 0
for score in scores:
ttl = ttl + score
n = len(scores)
avg = ttl / n
print("共有%d人, 總成績 :%3.0f , 平均成績 :%5.2f" % (n, ttl, avg))
```
enter score, to end just enter -1 and enter : 89
enter score, to end just enter -1 and enter : 99
enter score, to end just enter -1 and enter : 56
enter score, to end just enter -1 and enter : -1
共有3人, 總成績 :244 , 平均成績 :81.33
```python
#5 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" #del用來刪除list中的片段或清空整個list
print(fruits)
```
['櫻桃', '葡萄', '楊桃', '香蕉', '酪梨', '西瓜', '龍眼']
```python
```
```python
list4 = [100, 89, 79]
print(max(list4))
print(min(list4))
print(len(list4))
print(list4.count(79)) #count回傳項目在list中出現的次數
print(list4.index(79))
```
100
79
3
1
2
```python
#2 使用 for 迴圈讀取串列元素 <list4>
print(list4)
for n in list4:
print(n * 3, end = " ")
```
[100, 89, 79]
300 267 237
```python
for i in range(len(list4)):
print(i, list4[i], sep = ",") #sep = ”," 輸出時，以逗號隔開
```
0,100
1,89
2,79
```python
list1 = []
list2 = ["蘋果", "火龍果", "百香果"]
list3 = ["日本", "韓國", "新加坡"], ["保齡球", "網球", "籃球"]
print(list1)
print(list2)
print(list3)
```
[]
['蘋果', '火龍果', '百香果']
(['日本', '韓國', '新加坡'], ['保齡球', '網球', '籃球'])
```python
print("我最想去旅遊的地方是 %s" % list3[0][0])
```
我最想去旅遊的地方是 日本
```python
print(list2[0:2:1])
```
['蘋果', '火龍果']
```python
list2.append("奇異果") #append在list尾端添加一個新的項目
print(list2)
```
['蘋果', '火龍果', '百香果', '奇異果']
```python
list2.pop() #pop移除list中給定位置的項目，並回傳它。空白即最後一項
```
'奇異果'
```python
list2.pop(0)
```
'蘋果'
```python
list2[1] = "芒果"
print(list2)
```
['蘋果', '芒果', '百香果']
```python
list2.insert(0, "楊桃")
print(list2)
```
['楊桃', '蘋果', '芒果', '百香果']
```python
len(list1) #len用來計算字符串、列表、元组等…的長度
list1.count("楊桃")
```
0
### {綜合演練}
