Python试卷

3、写一个函数，计算一个给定的日期是该年的第几天。

    def getday(self,y=None,m=None,d=None):

       

        date = datetime(y,m,d)

        days = date.strftime('%j')

        return days

4、写一个函数，给定N，返回斐波那契数列第N项。

def getn_vlaue(self,n):

        if n<=2:

            return 1

        else:

            return self.getn_vlaue(n-1)+self.getn_vlaue(n-2)

5、从0到9中随机选择，生成1到10个随机数，组成集合A，同理生成集合B，输出A和B以及它们的并集和交集

def getnumberlist(self):

        a=[]

        b=[]

        j=k=0

        for x in xrange(0,10):

            j=int(random.random()*10)

            k=int(random.random()*10)

            a.append(j)

            b.append(k)

        print u'集合a:',a

        print u'集合b:',b

        return a,b

   

    def getendlistj(self,a,b):#并集

        c = a+b

        new_c = []

        for x in xrange(0,len(c)):

            temp = c[x]

            if temp not in new_c:

                new_c.append(temp)

               

        print u'并集:',new_c

    def getendlistb(self,a,b):#交集

        new_a =[]

        new_b = []

        new_c =[]

       

        for x in xrange(0,len(a)):

            temp = a[x]

            if temp not in new_a:

                new_a.append(temp)

               

        for x in xrange(0,len(b)):

            temp = b[x]

            if temp not in new_b:

                new_b.append(temp)

        j = len(new_a) if len(new_a)<len(new_b) else len(new_b)

        for x in xrange(0,j):

            temp = new_b[x]

            if temp in new_a:

                new_c.append(temp)

               

                

        print u'交集:',new_c

6、给定一个整数N，判断N是否为素数

    def getprime(self,n):

        if n<=3:

            print  u'是素数'

        else:

            i=0

            for x in xrange(2,n):

                if n%x==0:

                    i+=1

                else:

                    i=i

            if i==0:

                print  u'是素数'

            else:

                print  u'不是素数'
