应同学要求，写了一个爬托福考试空闲考位的脚本。这是第一次真正用Python3写。
通过调用get_seat_status，传入省名（如’Jiangsu’），时间（如’201104′），您可以得到这样的数据结构：
[ [datetime.datetime(2011, 4, 23, 10, 0), 'STN80085B', '南通市教育装备与勤工俭学管理中心', '1415', True],
[datetime.datetime(2011, 4, 23, 10, 0), 'STN80086A', '扬州大学', '1415', True]]
[datetime.datetime(2011, 4, 23, 10, 0), 'STN80086A', '扬州大学', '1415', True]]
下面是一个多线程调用的例子：
#! /usr/bin/python3
import threading
import pprint
from toeflgraber import get_seat_status
# 查询江浙沪 2011年3月和4月的考位
locations = ['Jiangsu', 'Shanghai', 'Zhejiang']
months = ['201103', '201104']
def descartes(x, y):
for i in x:
for j in y:
yield (i, j)
lock = threading.RLock()
tasks = len(locations) * len(months)
e = threading.Event()
results = []
def task(location, month):
global results, tasks
all_seats = get_seat_status(location, month)
available_seats = filter(lambda x: x[4], all_seats)
with lock:
results.extend(available_seats)
tasks -= 1
if tasks == 0:
e.set()
for t in descartes(locations, months):
t = threading.Thread(target=task, args=t)
t.daemon = True
t.start()
e.wait()
pprint.pprint(results)
import threading
import pprint
from toeflgraber import get_seat_status
# 查询江浙沪 2011年3月和4月的考位
locations = ['Jiangsu', 'Shanghai', 'Zhejiang']
months = ['201103', '201104']
def descartes(x, y):
for i in x:
for j in y:
yield (i, j)
lock = threading.RLock()
tasks = len(locations) * len(months)
e = threading.Event()
results = []
def task(location, month):
global results, tasks
all_seats = get_seat_status(location, month)
available_seats = filter(lambda x: x[4], all_seats)
with lock:
results.extend(available_seats)
tasks -= 1
if tasks == 0:
e.set()
for t in descartes(locations, months):
t = threading.Thread(target=task, args=t)
t.daemon = True
t.start()
e.wait()
pprint.pprint(results)
Enjoy it.
