list1[] =
print(list1)
list1[][][] = '?'
print(list1)

2.列表的排序（sort）

print(list4)

5.列表的匹配

list1 = ['1.a','2.b','3.c','4.d']
list2 = ['1.I','2.you','3.he/she','4,it']
list3 = [name + ':' + slame[:]for name in list1 for slame in list2 if slame[] ==name[]]
for each in list3:
    print(each)

6.列表推倒式[有关A的表达式for A in B]

list1 = [x**2 for x in range(10)]
print(list1)
list1 = []
for x in range(10):
    list1.append(x**2)
print(list1)
