print(list_1[2])
list_1[2]="xia" #添加一个元素
print(list_1)
print("Wellcome to there ",list_1[0])
print("Wellcome to there ",list_1[1])
print("Wellcome to there ",list_1[2])
for i in ("chen","Ronin","Jimi"):  遍历插入元素
    list_1.append(i)
print(list_1)
list_1.insert(0,"chun") #在选择的位置插入元素
list_1.insert(3,"chun")
list_1.append("qing")
print(list_1)
for i in list_1:
    print("Wellcome to there ",i)

num_bg=0
