标题: 新人求助 python74课多线程
我用的是python3
这是代码
import urllib.request,time,_thread
def get_content(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))

time_start=time.time()
data=[]
for i in range(30):
print('request movie:',i)
_thread.start_new_thread(get_content,(i,))
input('press ENTER to exit...\n')

运行结果是这样的：
request movie: 0
request movie: 1
request movie: 2
request movie: 3
request movie: 4
request movie: 5
request movie: 6
request movie: 7
request movie: 8
request movie: 9
request movie: 10
request movie: 11
request movie: 12
request movie: 13
request movie: 14
request movie: 15
request movie: 16
request movie: 17
request movie: 18
request movie: 19
request movie: 20
request movie: 21
request movie: 22
request movie: 23
request movie: 24
request movie: 25
request movie: 26
request movie: 27
request movie: 28
request movie: 29
press ENTER to exit...

请求失败了吧，豆瓣api现在接口频率降低了，它的官方文档里有说

你这个报错不全，没有输出必要的信息

作者: yy123 时间: 2018-3-22 16:49
嗯报错太多了就没都复制下来
那我的代码应该没问题把
还有个问题就是func(**kargs) 输出的顺序是按照参数顺序输出的，并不是无序的，这个是因为python3的关系吗
谢谢了

py3的字典的确改过
