Closing python comand subprocesses

Question

I want to continue executing commands after closing the subprocess. I have the following code but fsutilit is not executing. How can i do this?

import os
from subprocess import Popen, PIPE, STDOUT

os.system('mkdir c:\\temp\\vhd')
p = Popen( ["diskpart"], stdin=PIPE, stdout=PIPE )
p.stdin.write("create vdisk file=c:\\temp\\vhd\\test.vhd maximum=2000 type=expandable\n")
p.stdin.write("attach vdisk\n")
p.stdin.write("create partition primary size=10\n")
p.stdin.write("format fs=ntfs quick\n")
p.stdin.write("assign letter=r\n")
p.stdin.write("exit\n")
p.stdout.close
os.system('fsutil file createnew r:\dummy.txt 6553600') #this doesn´t get executed

At least I think you need to change your code to look like this:

import os
from subprocess import Popen, PIPE

os.system('mkdir c:\\temp\\vhd')
p = Popen(["diskpart"], stdin=PIPE, stdout=PIPE, stderr=PIPE)
p.stdin.write("create vdisk file=c:\\temp\\vhd\\test.vhd maximum=2000 type=expandable\n")
p.stdin.write("attach vdisk\n")
p.stdin.write("create partition primary size=10\n")
p.stdin.write("format fs=ntfs quick\n")
p.stdin.write("assign letter=r\n")
p.stdin.write("exit\n")
results, errors = p.communicate()
os.system('fsutil file createnew r:\dummy.txt 6553600')

From the documentation forPopen.communicate() :

: stdin. stdout stderr, . , . , ​​ , None, .

p.communicate() p.wait(), Popen.wait()

. stdout = PIPE / stderr = PIPE, , OS, . (), .
