num break 2.7 历程 it is log 学习 pre
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
