3.用map来处理字符串列表,把列表中所有人都变成sb,比方alex_sb

name=['alex','wupeiqi','yuanhao','nezha']
name1 =[]
def func(s):
    return (s+"_sb")

t = map(func,name)  # t是迭代器
for i in t:
    print(i)
    name1.append(i)
print(name1)

4.用filter函数处理数字列表，将列表中所有的偶数筛选出来

num = [1,3,5,6,7,8]
def func(s):
    return s % 2 == 0
t = filter(func,num)    #迭代器
for i in t:
    print(i)
