Hide CMD call window

[tester_V]

Greetings!
Running my script every hour on a windows machine.
The script has a “arp-a” cmd call and a window pops up that is very annoying .
How I can suppress the pop up window?
code:

1 2 3 4 5 6 7

with open(fl,'w') as e :     cmd = "arp -a"     returned_output = subprocess.check_output(cmd)     ln = returned_output.decode("utf-8")     ln=ln.strip()     print(ln)     e.write(ln)

Thank you.

Is it the same if you use

1	cmd = ['arp', '-a']

When i test your code no cmd window pop up.
This correct and normal behavior,what are you using to schedule code every hour?
If you run code from command line python arp_code.py,dos still cmd window pop up?

Can also change to this,same no cmd window shall pop up.

1 2 3 4 5 6

import subprocess   with open('arp.txt', 'w') as fp:     output = subprocess.run(['arp', '-a'], encoding='utf-8', capture_output=True)     #print(output.stdout.strip())     fp.write(output.stdout.strip())

windows ...

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

import subprocess     def arp():     """     Run arp -a and return the stripped output.     Window creation is prevented.     """     flags = subprocess.CREATE_NO_WINDOW           return subprocess.run(         ["arp", "-a"],         capture_output=True,         encoding="utf8",         creationflags=flags,     ).stdout.strip()

Yes, DOS window was popping up very hour, I understand it was running " arp -a".
Outstanding! It is what I wanted/needed.
You guys (girls?) are great!
Thank you!

I was happy too early
it still pops up.
I'm not sure how to incorporate "Dead_YEY" snippet correctly to the code I have.
I tried to modify it but it does not work:

1 2 3 4 5 6 7

import subprocess from subprocess import CREATE_NO_WINDOW    flags = subprocess.CREATE_NO_WINDOW with open('C:\\somedir\\ARP_A.txt','w') as e :     output = subprocess.run(['arp', '-a'], encoding='utf-8', capture_output=True)     creationflags=flags        output.write(output.stdout.strip())

creation_flags=flags doesn't do anything in your code because you put it in the wrong place.. This runs fine for me. No window popping up on windows 10.

1 2 3 4 5 6 7 8 9 10

import subprocess   print(     subprocess.run(         ["arp", "-a"],         encoding="utf-8",         capture_output=True,         creationflags=subprocess.CREATE_NO_WINDOW,   # Notice this is a function argument, not variable assignment     ) )

[tester_V]

it works, no pop ups!
deanhystad, you are DA MAN!

Thank you!

Dead EYE is da man. You need to develop a more critical eye so you can spot your own coding errors.
