单个start_url中的随机数

Question

I have one start URL and only want to crawl one page, however I want to randomly choose that page by entering a random number between 1 and 50 in the start_url:

start_urls = ["http://www.modcloth.com/shop/bedding?sorting=loved&page=1"]

where page= Random Number

Answer 1

You can use the standard random.randint library function.

from random import randint

start_urls = ["http://www.modcloth.com/shop/bedding?sorting=loved"
              "&page={0}".format(randint(1,50))]
