Python学习之路

第一例：

# -*- coding:utf-8 -*-
from pip._vendor.distlib.compat import raw_input

user = raw_input("plaese input user name:")
pwd = raw_input("plaese input password:")
if user == "allen" and pwd == "allen":
    print ("登录成功！")
else:
    print ("登录失败！")


第二例：

100块钱，公鸡5块一只，母鸡3块一只，3只小鸡一块钱
x+y+z=100;
5x+3y+z/3=100；

# -*- coding:utf-8 -*-

for x in range(1,20):
    for y in range(1,33):
        z = 100-x-y
        if (z % 3 == 0) and (x * 5 + y * 3 + z / 3 == 100):
            s = "公鸡：%d只: 母鸡: %d只: 小鸡: %d只" % (x,y,z)
            print(s)
