阿新 • • 發佈：2020-07-19
一.基本資料型別
整數：int
字串：str(注：\t等於一個tab鍵)
布林值： bool
列表：list （元素的集合）
列表用[]
元祖：tuple
元祖用（）
字典：dict
注：所有的資料型別都存在想對應的類列裡
二.列表所有資料型別：
基本操作：
- 索引
- 切片
- 追加
- 刪除
- 長度
- 切片
- 迴圈
- 包含
三.所有列表資料型別舉例
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 |
#!/usr/bin/env python
# -*- coding:utf-8 -*-
#append追加
name_list=["zhangyanlin","suoning","nick"]
name_list.append('zhang')
print(name_list)
#count制定字元出現幾次
name_list=["zhangyanlin","suoning","nick"]
name_list.append('zhang')
name_list.append('zhang')
name_list.append('zhang')
print(name_list.count('zhang'))
#extend可擴充套件，批量往裡加資料
name_list=["zhangyanlin","suoning","nick"]
name=["aylin","zhang","yan","lin"]
name_list.extend(name)
print(name_list)
#index找到字元所在的位置
name_list=["zhangyanlin","suoning","nick"]
print(name_list.index('nick'))
#insert插入，往索引裡面插入值
name_list=["zhangyanlin","suoning","nick"]
name_list.insert(1,"zhang")
print(name_list)
#pop在原列表中移除掉最後一個元素，並賦值給另一個變數
name_list=["zhangyanlin","suoning","nick"]
name=name_list.pop()
print(name)
#remove移除,只移除從左邊找到的第一個
name_list=["zhangyanlin","suoning","nick"]
name_list.remove('nick')
print(name_list)
#reverse反轉
name_list=["zhangyanlin","suoning","nick"]
name_list.reverse()
print(name_list)
#del刪除其中元素,刪除1到3之間的
name_list=["zhangyanlin","suoning","nick"]
delname_list[1:3]
print(name_list)
|
四.索引
| 1 2 |
name_list=["zhangyanlin","suoning""aylin""nick"]
print(name_list[0])
|
五.切片
| 1 2 |
name_list=["zhangyanlin","suoning""aylin""nick"]
print(name_list[0:2])
|
六.總長度len
| 1 2 |
name_list=["zhangyanlin","suoning""aylin""nick"]
print(name_list[1:len(name_list)])
|
七.for迴圈
| 1 2 3 |
name_list=["zhangyanlin","suoning""aylin""nick"]
foriinname_list:
print(i)
