#1 Created at ... [Delete] [Delete and Lock User]

# -*- coding: utf-8 -*-
#def is_odd(n):
#    return n % 2 == 1
g = lambda n: n % 2 ==1
# 貌似这样写比较啰嗦，看来还得向大家学习
L = list(filter(g, range(1, 20)))

#2 Created at ... [Delete] [Delete and Lock User]

直接这样就好了 L = list(filter(lambda x:x%2, range(1, 20)))

%2是取余数，余数只有0和1
