Question

my python code like this:

#!/usr/bin/env python
import threading
from time import sleep,ctime
loops=[4,2]

def loop(nloop,nsec):
    print 'start loop',nloop,'at:',ctime()
    sleep(nsec)
    print 'loop',nloop,'done at:',ctime()

def main():
    print 'starting at:',ctime()
    threads=[]
    nloops = range(len(loops))

    for i in nloops:
        t = threading.Thread(target = loop, args = (i,loops[i]))
        threads.append(t)
    for i in nloops:
        threads[i].start()
    for i in nloops:
        threads[i].join()
    print 'all Done at:',ctime()
if __name__ == '__main__':
    main()

but python output is:

t = threading.Thread(target = loop, args = (i,loops[i]))
AttributeError: 'module' object has no attribute 'Thread'
Exception AttributeError: '_shutdown' in <module 'threading' 

i reinstall python ,but this issue still have ,how to fix it?

Answer 1

I bet you have a local file named threading.py, and it’s masking the system threading module.

You can verify this by printing threading.__file__:

import threading
print threading.__file__

to get the file path of the module that is being imported.

Rename it, or delete it, to fix this.
