urls = []
def create_url(id):

    url = "http://jandan.net/ooxx/page-"+str(id)+"#comments"
    urls.append(url)


nums = []

page = int(input("請輸入要爬取的頁數:"))

while page:
    num = 107-page
    nums.append(num)
    page = page - 1

for i in nums:
    create_url(i)

for each in urls:
    html = urlopen(each)
    bsObj = BeautifulSoup(html,"html.parser")

    imageLocation = bsObj.find_all("img")

    temp = random.uniform(20, 10) 
    for each in imageLocation:
        location = "http:" + each.get('src')
        print(location)
        temp += 3
        urlretrieve(location, '%s.jpg' % temp)
    print(imageLocation)
