##########  列表  #########
name_list = ["eire","alex","tony"]
# 索引
print(name_list[0])
# 切片
print(name_list[1:2])name_list = ["eire","alex","tony"]
name_list.append("seven")
print (name_list)
print (name_list.count('seven'))
teme = ["11","22","33"]
name_list.extend(teme)
print(name_list)

a1 = name_list.pop()
print (name_list)
print (a1)
name_list.remove('seven')
print (name_list)
name_list.reverse()
print (name_list)
# 循环
for i in name_list:
    print (i)
    
# 列表内部提供的其他功能
# 1.append ：后面追加
name_list.append("save")
print (name_list)
# 2.count：统计元素出现的次数
name_list = ["eire","alex","tony"]
name_list.append("seven")
name_list.append("seven")
name_list.append("seven")
print (name_list)
# 3.extend 扩展  # iterable 可迭代的
name_list = ["eire","alex","tony"]
name_list.append("seven")
print (name_list)
print (name_list.count('seven'))
teme = ["11","22","33"]
# 扩展、批量添加
name_list.extend(teme)
print(name_list)
# 获取指定元素的索引位置
print (name_list.index('alex'))
# 向指定元素位置插入数据
name_list.insert(1,'shin')
print (name_list)
# 在原列表中移除最后一个元素，并将其赋值给 a1
a1 = name_list.pop()
print (name_list)
print (a1)
# 移除某个元素
name_list.remove('seven')
print (name_list)
# 翻转
name_list.reverse()
