python基础学习 day 1

　　初学python，记录下自己的历程~

　　了解了一下python的基本概念，现在使用的比较多的就是python2.7

　　学习了if语句和两个经典的循环语句

#关于if语句的应用
name = raw_input('input name')
age = input('input age')
#也可以用input
salary = raw_input('salary')

#使用if语句永远只有一个结果，满足条件即结束
if age > 60:
    msg = 'you are too old'
elif age > 30:
    msg = 'you are not young'
else:
    msg = 'you are still young'

print'''
information of %s:
      name:%s
       age:%d
    salary:%s
________________________
%s 

''' %(name, name, age ,salary, msg)#必须一一对应

#关于for循环(猜年龄)
real_age = 18

for i in range(10):
    age = input('age:')
    if age > real_age:
        print 'think smaller'
    elif age < real_age:
        print 'think bigger'
    else:
        print 'you are right'
        break
    print 'you still have %s shots' % (9 - i)

#关于while循环（选定打印的数）
import sys
num = 0
count = 0

while count <=1000:
    if count == num:
        print 'there is the number', count
        while num <= count:
            num = input('which number do you want? inuput 0 to exist')
            if num == 0:
                sys.exit()
            if num <= count:            
                print 'it is over'        
    else:
        print 'loop:', count
        count += 1
else:
    print 'loop:', count
