think python学习心得-（4）有返回函数

练习题

6-1

      def compare(x,y):
      if x>y:
      return 1
      elif x==y:
      return 0
      else:
      return -1
      a=[int(i) for i in raw_input('please input 2 number: ').split()]
      print compare(a[0],a[1])
  
 

      a=[int(i) for i in raw_input('please input 2 number: ').split()]
      语句可以实现用空格隔开的多个数据的输入，就像matlab中的向量一样，很好用！
  
 

      import math
      def hypotenuse(x,y):
      return math.sqrt(x**2+y**2)
      a=[int(i) for i in raw_input('please input 2 number: ').split()]
      print hypotenuse(a[0],a[1])
  
 

      def is_between(x,y,z):
      if x<=y:
      if y<=z:
      return True
      else:
      return False
      else:
      return False
      a=[int(i) for i in raw_input('please input 3 number: ').split()]
      print is_between(a[0],a[1],a[2])
  
 

返回值是int类型的90

6-7

      def is_power(a,b):
      if a%b==0:
       a=a/b
      if a>b:
       is_power(a,b)
      elif a==b:
      print 'yes'
      else:
      print 'no'
      else:
      print 'no'
      print 'Please number a and b'
      x=int(raw_input())
      y=int(raw_input())
      is_power(x,y)
  
 

      flag=[]
      def gcd(a,b):
       m=min(a,b)
      for i in range(m):
      if a%(i+1)==0:
      if b%(i+1)==0:
       flag.insert=(i,i)
      print 'please input a and b to get GCD'
      x=int(raw_input())
      y=int(raw_input())
      gcd(x,y)
      print flag
