HTML code is as follows, I am a beginner, recently learned multithreading, wrote the above code of practice, the purpose is to simulate multiple threads can communicate with each other, sharing data, but in each system, get the running result of the different... Wish you a great god can help me with a humbug,


The import multiprocessing

Def download_data (q) :
# download data
Data=https://bbs.csdn.net/topics/[44] 11, 22, 33,
Print (' download... ')

For temp in data:
Q.p ut (temp)
Print (' the download is complete.. ')


Def analysis_data (q) :
# to get the data
Waitting=list ()

# data
While True:
Data=(https://bbs.csdn.net/topics/q.get)

Waitting. Append (data)
If q.e mpty () :
Break
Print (waitting)




Def the main () :
# to create a file
Q=multiprocessing Queue ()

P1=multiprocessing. Process (target=download_data, args=(q,))
P2=multiprocessing. Process (target=analysis_data, args=(q,))

P1. The start ()
P2. The start ()

If __name__=="__main__ ':

This is the result of running under Ubuntu:



This is the result of running under Windows 10:

Why missing picture?

CodePudding user response:

Zha couldn't show the picture?

Which means that the final want to output a list of,22,33,44 [11] same
Win it is a normal
But in Ubuntu, only [11]

CodePudding user response:

Friend,
I also recently in the study, and I said my idea, not to, you when a train of thought for your reference, I don't think this code is rigorous, ubuntu and Windows running results are possible in my opinion, only the ubuntu without insert judged to be empty when I was 22, so the output termination loop, but may be because of the difference of running speed, Windows without this happening, I think you can add delay time of 0.1 s on while True, make sure to add and remove, but it is not good, another method, if where to==44 can also, this method, it goes to the last value so far out of circulation,
