列表是python內建資料型別，列表中的元素可以增、刪、改，類似java中的陣列

一、列表定義

列表用[ ]定義

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

二、列表訪問

通過索引訪問列表元素
訪問最後一個元素：course[-1]

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

三、列表修改

四、列表新增

1、追加元素

course.append(“HTMl”)

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

2、插入元素

course.insert(0,“Css”)

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

五、列表刪除

1、刪除最後一個元素-pop()

course.pop()

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

 

2、刪除指定位置元素-pop(index)

course.pop(index)

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

3、刪除指定位置元素-del語句

del course[0]

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

4、移除某個元素-remove(obj)

course.remove(“Java”)

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