The right program is as following,everything is ok. import requests import threading import queue
class webdata(object):
def __init__(self,name):
self.jobs=queue.Queue()
for x in name:
url='http://stockhtm.finance.qq.com/sstock/ggcx/%s.shtml' %x
self.jobs.put(url)
def download(self):
while not self.jobs.empty():
try:
url = self.jobs.get()
print(requests.get(url).status_code,url)
print(threading.currentThread())
self.jobs.task_done()
except:
print("wrong",url)
self.jobs.task_done()
def run(self):
for i in range(3):
threading.Thread(target=self.download).start()
self.jobs.join()
print("i am over")
name=['600000', '000001', '600319', '600531','600661', '600983', '600202',
'600149']
x=webdata(name)
x.run()
question1:
when i delete the line of `self.jobs.join()` ,the program will never finished
,why?
import requests
import threading
import queue
class webdata(object):
def __init__(self,name):
self.jobs=queue.Queue()
for x in name:
url='http://stockhtm.finance.qq.com/sstock/ggcx/%s.shtml' %x
self.jobs.put(url)
def download(self):
while not self.jobs.empty():
try:
url = self.jobs.get()
print(requests.get(url).status_code,url)
print(threading.currentThread())
self.jobs.task_done()
except:
print("wrong",url)
self.jobs.task_done()
def run(self):
for i in range(3):
threading.Thread(target=self.download).start()
self.jobs.join()
print("i am over")
name=['600000', '000001', '600319', '600531','600661', '600983', '600202',
'600149']
x=webdata(name)
x.run()
never quit from the thread ,why?
question2:
I can get every son-thread thread number with
`print(threading.currentThread()) `,how can i get the main thread number in
the program?
