import urllib.request,time

time_start=time.time()
data=[]
for i in range(30):
    print('reuest movie:',i)
    id=1764796+i
    url='https://api.douban.com/v2/movie/subject/%d'%id
    d=urllib.request.urlopen(url).read()
    data.append(d)
    print(i,time.time()-time_start)
print('data',len(data))


运行结果如下：
reuest movie: 0
0 0.7348060607910156
reuest movie: 1

把请求地址print出来，然后在浏览器里看下，有些影片是被屏蔽了，这种要用异常处理去跳过它 ...

经过异常处理已解决，谢谢。
但下面这个多线程的程序不能正确运行，麻烦再帮我看一下
import urllib.request, time, threading

def get_content(i):
    id=1764796+i
    try:
        url='https://api.douban.com/v2/movie/subject/%d'%id
        d=urllib.request.urlopen(url).read()
        data.append(d)
        print(i,time.time()-time_start)
    except:
        print('Not Found')
    print('data',len(data))

time_start = time.time()
data = []
for i in range(30):
    print ('request movie:', i)
    threading._start_new_thread(get_content, (i,))

input('press ENTER to exit...\n')
