Python: Hunting numbers

Abstract: This script is used for hunting all even, odd, or prime numbers with a given scale.


The script:

#define the class
class hunt_numbers(object):

    def __init__(self, start, end):
        self.start = start
        self.end = end

    def even_numbers(self):
        num=self.start
        arr=[]
        while num<=self.end:
            if(num%2 == 0):
                arr.append(num)
            num=num+1
        return arr

    def odd_numbers(self):
        num=self.start
        arr=[]
        while num<=self.end:
            if(num%2 == 1):
                arr.append(num)
            num=num+1
        return arr

    def judge_prime(self, num):
        found=1
        for i in range(2,num):
            if (num % i == 0) :
                found=0
                break
        return found

    def prime_numbers(self):
        pool=range(self.start, self.end)
        pool.append(self.end)
        arr=[]
        for index,num in enumerate(pool):
            if (self.judge_prime(num)==1):
                arr.append(num)
        return arr
