列表是python内置数据类型，列表中的元素可以增、删、改，类似java中的数组

### 一、列表定义 ###

列表用\[ \]定义

course=["Python","Linux","Java","C++"]
    print(course)

![坚持比努力更重要][20181217203019184.]

### 二、列表访问 ###

通过索引访问列表元素  
**访问最后一个元素：course\[-1\]**

course=["Python","Linux","Java","C++"]
    print(course[2])
    print(course[-1])

### 三、列表修改 ###

### 四、列表添加 ###

#### 1、追加元素 ####

**course.append(“HTMl”)**

course=["Python","Linux","Java","C++"]
    course.append("HTMl")
    print(course)

![坚持比努力更重要][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hqdTIy_size_16_color_FFFFFF_t_70 2]

#### 2、插入元素 ####

**course.insert(0,“Css”)**

course=["Python","Linux","Java","C++"]
    course.insert(0,"Css")
    print(course)

![坚持比努力更重要][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hqdTIy_size_16_color_FFFFFF_t_70 3]

### 五、列表删除 ###

#### 1、删除最后一个元素-pop() ####

**course.pop()**

course=["Python","Linux","Java","C++"]
    course.pop()
    print(course)

#### 2、删除指定位置元素-pop(index) ####

**course.pop(index)**

course=["Python","Linux","Java","C++"]
    course.pop(0)
    print(course)

#### 3、删除指定位置元素-del语句 ####

**del course\[0\]**

course=["Python","Linux","Java","C++"]
    del course[0]
    print(course)

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2hqdTIy_size_16_color_FFFFFF_t_70 6]

#### 4、移除某个元素-remove(obj) ####

**course.remove(“Java”)**

course=["Python","Linux","Java","C++"]
    course.remove("Java")
    print(course)
