初学爬虫，requests抓取不到网页

Question

直接用requests.get就可以

response = requests.get("https://movie.douban.com/top250?start=0&filter=")
print(response.text)

但是我按照教程上的步骤就不可以，是我的代码哪里出了问题吗？

import requests
from requests.exceptions import RequestException

def get_one_page(url):
    try:
        response = requests.get(url)
        if response.status_code == 200:
            return response.text
        return None
    except RequestException:
        return None

def main():
    url = 'https://movie.douban.com/top250?start=0&filter='
    html = get_one_page(url)
    print(html)

if __name__ == '__main':
    main()

Answer 1

倒数第二行写错了：
应该是 if name=="__main__"
