I am writing a 2-process program to echo a line of raw input while heartbeat once every second.
Here is the code:
from multiprocessing import Process
import time
def echo():
while True:
a = raw_input('type something')
print 'you typed: ', a
def ticking():
while True:
time.sleep(1)
print 'hello'
if __name__ == '__main__':
p1 = Process(target=echo, args=())
p1.start()
p2 = Process(target=ticking, args=())
p2.start()
p1.join()
p2.join()
When I run this script, there is always an EOFError thrown.
Traceback (most recent call last):
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/multiprocessing/process.py", line 258, in _bootstrap
self.run()
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/multiprocessing/process.py", line 114, in run
self._target(*self._args, **self._kwargs)
File "t.py", line 7, in echo
a = raw_input('type something')
EOFError: EOF when reading a line
What is wrong here? How to correct this?
