Question

我试图使用cygwin来运行我的Python代码。该脚本应该启动一个线程并对其进行处理。但它不知何故不起作用。作为一个最小的例子，我使用了这里的代码＆＃39; http://www.saltycrane.com/blog/2008/09/simplistic-python-thread-example/＆＃39;。正如您在下面的日志中所看到的，Thread.start()结束了cygwin中的Pyhton交互式输入而没有任何消息。相反，在另一台机器上，程序按预期运行。我期待一个cygwin问题，但是在cygwin上重新安装Python包并没有帮助。

想法？

$ python
Python 2.7.12 (default, Oct 10 2016, 12:56:26)
[GCC 5.4.0] on cygwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import time

def myfunc(i):
    print "sleeping 5 sec from thread %d" % i
    time.sleep(5)
    print "finished sleeping from thread %d" % i

for i in range(10):
    t = Thread(target=myfunc, args=(i,))
    t.start()
>>> from threading import Thread
>>>
>>> def myfunc(i):
...     print "sleeping 5 sec from thread %d" % i
...     time.sleep(5)
...     print "finished sleeping from thread %d" % i
...
>>> for i in range(10):
...     t = Thread(target=myfunc, args=(i,))
...     t.start()
...

以这种方式改写
cat prova-python.py

#!/usr/byn/python
import time,threading

def myfunc(i):
    print "sleeping 5 sec from thread %d" % i
    time.sleep(5)
    print "finished sleeping from thread %d" % i

for i in range(10):
    t = threading.Thread(target=myfunc, args=(i,))
    t.start()

有效，但第二阶段的输出可能在线程之间重叠。

 $ python prova-python.py
sleeping 5 sec from thread 0
sleeping 5 sec from thread 1
sleeping 5 sec from thread 2
sleeping 5 sec from thread 3
sleeping 5 sec from thread 4
sleeping 5 sec from thread 5
sleeping 5 sec from thread 6
sleeping 5 sec from thread 7
sleeping 5 sec from thread 8
sleeping 5 sec from thread 9
finished sleeping from thread 0
finished sleeping from thread 2
finished sleeping from thread 1
finished sleeping from thread 3
finished sleeping from thread 4
finished sleeping from thread 5
finished sleeping from thread 6
finished sleeping from thread 9finished sleeping from thread 8finished sleeping from thread 7

Python线程并不在cygwin上运行
