新手学python 多线程 传递参数 问题
#!/usr/bin/pythonimport threading
import thread
import sys
import time
def func(x):
for i in range(x,10 +1):
print i
time.sleep(1)
t1 = threading.Timer(0,func(5))
t2 = threading.Timer(0,func(4))
t1.start()
t2.start()
这个多线程原本没有加参数是可以的，现在传递一个参数进去 变成了 单线程，请哥哥们 帮忙修改一下。

属于传参错误，看文档class threading.Timer(interval, function, args=[], kwargs={})
Create a timer that will run function with arguments args and keyword arguments kwargs, after interval seconds have passed.
一个例子，传参用list#!/usr/bin/env python
# -*- coding: utf-8 -*-
import sys
import time
import threading
def counter(identity, limit):
for n in range(limit):
# stderr无缓存，避免线程间交叉输出
sys.stderr.write('id = {}, cnt = {}\n'.format(identity, n))
# print 'id = {}, cnt = {}'.format(identity, n)
time.sleep(0.5)
def main():
for i in range(3):
t = threading.Timer(3, counter, )
t.start()
if __name__ == '__main__':
main()Python2.7执行，可能输出id = 0, cnt = 0
id = 2, cnt = 0
id = 1, cnt = 0
id = 2, cnt = 1
id = 0, cnt = 1
id = 1, cnt = 1
id = 2, cnt = 2
id = 0, cnt = 2
id = 1, cnt = 2
id = 1, cnt = 3
id = 2, cnt = 3
id = 2, cnt = 4 回复 2# timespace
哥哥 谢谢你了，你给的例子太好了，一看就明白。
俺以后学习细心一些多看手册
