    例:

    name_list = ['alex', 'seven', 'eric']
    或
    name_list = list(['alex', 'seven', 'eric'])

    基本操作:

    • 索引

    • 切片

    • 追加

    • 删除

    • 长度

    • 切片

    • 循环

    • 包含

    详细介绍 如下 ~

    append 追加

    user_list = ['xmzncc','asd','fcc']
    user_list.append('123')
    print(user_list)

    clear 清空

    user_list = ['xmzncc','asd','fcc']
    user_list.clear()
    print(user_list)

    copy 拷贝(浅拷贝)

    user_list = ['xmzncc','asd','fcc']
    v = user_list.copy()
    print(v)

    count 计数

    user_list = ['xmzncc','asd','fcc','xmzncc']
    v = user_list.count('xmzncc')
    print(v)

    extend 扩展原列表

    user_list = ['xmzncc','asd','fcc']
    user_list.extend(['qwe'])
    print(user_list)

    index 查找元素索引

    user_list = ['xmzncc','asd','fcc']
    v = user_list.index('xmznc')
    print(v)

    pop 删除索引,获取元素

    user_list = ['xmzncc','asd','fcc']
    v = user_list.pop(0)
    print(v)
    print(user_list)

    remove 删除元素

    user_list = ['xmzncc','asd','fcc']
    v = user_list.remove('xmzncc')
    print(v)
    print(user_list)

    reverse 翻转

    user_list = ['xmzncc','asd','fcc']
    user_list.reverse()
    print(user_list)

    sort 排序
    从大到小

    nums = [11,12,13,4,6,7,99,101]
    nums.sort()
    print(nums)

    从小到大

    nums = [11,12,13,4,6,7,99,101]
    nums.sort(reverse=True)
    print(nums)
