Hi,
I'm having a very strange issue with subprocess.Popen. I'm using it
to call several times an external exe and keep the output in a list.
Every time you call this external exe, it will return a different
string. However, if I call it several times using Popen, it will
always return the SAME string. =:-O It looks like Popen is returning
always the same value from stdout, without recalling the exe.
This is my code:
------------------------------------------------------------------------------------------------------------------------------------
def get_key():
from subprocess import Popen, PIPE
args = [C_KEY_MAKER, '/26', USER_NAME, ENCRYPTION_TEMPLATE, '0', ]
process = Popen(args, stdout=PIPE)
output = process.communicate()[0].strip()
return output
print get_key() # Returns a certain string
print get_key() # Should return another string, but returns the
same!
-------------------------------------------------------------------------------------------------------------------------------------
What on Earth am I doing wrong?!
