python三个函数与lambda结合

filter函数

1 people = ['tanglaoer_sb', 'chenlaosan_sb', 'linlaosi', 'wanglaowu_sb']
2 res = filter(lambda n:not n.endswith('sb'),people)
3 print(list(res))

map函数

1 msg = 'tanglaoer'
2 print(list(map(lambda x:x.upper(),msg))) #['T', 'A', 'N', 'G', 'L', 'A', 'O', 'E', 'R']

reduce函数

1 from functools import reduce
2 num_list = [1,2,3,100]
3 print(reduce(lambda x,y:x+y,num_list)) #106
