线程池传参问题

改用线程池代码,单个参数

复制代码
import time
import threadpool  
def sayhello(str):
    print "Hello ",str
    time.sleep(2)

name_list =['xiaozi','aa','bb','cc']
start_time = time.time()
pool = threadpool.ThreadPool(10) 
requests = threadpool.makeRequests(sayhello, name_list) 
[pool.putRequest(req) for req in requests] 
pool.wait() 
print '%d second'% (time.time()-start_time)
复制代码

当函数有多个参数的情况,函数调用时第一个解包list,第二个解包dict,所以可以这样:

复制代码
def hello(m, n, o):
    """"""
    print "m = %s, n = %s, o = %s"%(m, n, o)
     
 
if __name__ == '__main__':
     
   # 方法1  
    lst_vars_1 = ['1', '2', '3']
    lst_vars_2 = ['4', '5', '6']
    func_var = [(lst_vars_1, None), (lst_vars_2, None)]
    # 方法2
    dict_vars_1 = {'m':'1', 'n':'2', 'o':'3'}
    dict_vars_2 = {'m':'4', 'n':'5', 'o':'6'}
    func_var = [(None, dict_vars_1), (None, dict_vars_2)]    
     
    pool = threadpool.ThreadPool(2)
    requests = threadpool.makeRequests(hello, func_var)
    [pool.putRequest(req) for req in requests]
    pool.wait()
