关于python使用threadpool中的函数单个参数和多个参数用法举例

1.对单个元素的函数使用线程池:

# encoding:utf-8
__author__='xijun.gong'
import threadpool


def func(name):
    print 'hi {}\n'.format(name)

if __name__ == '__main__':
    data = ['xijun.gong', 'xijun', 'gxjun']
    pool = threadpool.ThreadPool(5)
    reqs = threadpool.makeRequests(func, data)
    [pool.putRequest(req) for req in reqs]
    pool.wait()

结果：

hi xijun.gong

hi xijun

hi gxjun

2.对于多个参数的情况使用方式：

# encoding:utf-8
__author__='xijun.gong'
import threadpool


def func(name):
    print 'hi {}\n'.format(name)

def add(a,b):
    print '{0}+{1}={2}'.format(a,b,(a+b))
if __name__ == '__main__':
    data = [((index,i),None) for index,i in enumerate(range(1,10,2))]#(index,i)也可以写成[index,i]
    pool = threadpool.ThreadPool(5)
    reqs = threadpool.makeRequests(add, data)
    [pool.putRequest(req) for req in reqs]
    pool.wait()

结果：

0+1=1
1+3=4
3+7=10
2+5=7
4+9=13

3.如果我们想不安参数顺序赋值，可以使用这种方式：

# encoding:utf-8
__author__='xijun.gong'
import threadpool


def func(name):
    print 'hi {}\n'.format(name)

def add(a,b):
    print '{0}+{1}={2}'.format(a,b,(a+b))
if __name__ == '__main__':
    data = [(None,{'b':index,'a':i}) for index,i in enumerate(range(1,10,2))]
    pool = threadpool.ThreadPool(5)
    reqs = threadpool.makeRequests(add, data)
    [pool.putRequest(req) for req in reqs]
    pool.wait()
