一些基础知识：

　　1、if __name__ == '__main__'的意思是：

　　　　当.py文件被直接运行时，if __name__ == '__main__'之下的代码块将被运行；当.py文件以模块形式被导入时，if __name__ == '__main__'之下的代码块不被运行。

　　2、在python执行py文件

    1. import sys #引入sys库体  
    2. sys.path.append("C://myPython") #往系统路径中加入自己存放py文件的地址 
      然后就可以开始通过import的方法导入相关的方法和内容了
    3. from test import * #从test.py文件中加载所有的内容。 

 

文件读写：

　　with open(r'f:\test\t1.txt','r') as f:
　　　　print f.read()　　　　　　读

　　f.close()　　　　关闭

　　with相当于try...catch；　　

　　按行读：

　　with open(r'f:\test\t1.txt','r') as f:
　　　　for l in f.readlines():
　　　　　　print l.strip()

　　f.close()

　　写文件：　　

　　with open(r'f:\test\t1.txt','w') as f:
　　　　f.write('abcde')

　　f.close()

序列化：

　　import cPickle as pickle　　引入包

　　with open(r'f:\test\t1.txt', 'wb') as f:
　　　　dic = 10
　　　　pickle.dump(dic, f)

　　f.close()

　　with open(r'f:\test\t1.txt', 'rb') as f:
　　　　aa = pickle.load(f)
　　　　print(aa)

　　f.close()

多线程：

　　

import random
import time,threading
def thread_run(urls):
　　for url in urls:
　　　　print "%s ---->>>> %s"%(threading.current_thread().name,url)
　　　　time.sleep(random.random())
　　print "thread %s end..."%threading.current_thread().name

t1 = threading.Thread(target=thread_run,name="Thread_1",args=(["url_1","url_2","url_3"],))
t2 = threading.Thread(target=thread_run,name="Thread_1",args=(["url_4","url_5","url_6"],))
t1.start()
t2.start()
t1.join()
t2.join()
print "end....."

　　

　//join是主线程等待子线程

　　

import random
import threading
import time
class myThread(threading.Thread):
    def __init__(self,name,urls):
        threading.Thread.__init__(self,name=name)
        self.urls = urls

    def run(self):
        for url in self.urls:
            print "%s ---->>> %s" %(threading.current_thread().name,url)
        print "%s ended..."%threading.current_thread().name

t1 = myThread(name="Thread_1",urls=["url_1","url_2","url_3"])
t2 = myThread(name="Thread_2",urls=["url_4","url_5","url_6"])
t1.start()
t2.start()
t1.join()
t2.join()
print "%s end...." %threading.current_thread().name

　　线程同步：

import random
import threading
import time
mylock = threading.RLock()
class myThread(threading.Thread):
    def __init__(self,name,urls):
        threading.Thread.__init__(self,name=name)
        self.urls = urls

    def run(self):
        for url in self.urls:
            mylock.acquire()
            print "%s ---->>> %s --" %(threading.current_thread().name,url)
            mylock.release()

t1 = myThread(name="Thread_1",urls=["url_1","url_2","url_3"])
t2 = myThread(name="Thread_2",urls=["url_4","url_5","url_6"])
t1.start()
t2.start()
t1.join()
t2.join()
print "%s end...." %threading.current_thread().name
