Wow, just found out this morning that the following
terms of:
import os
pr = os.popen("lpr", "w")
pr.write(month), pr.write(" "),
pr.write("\t\tLine ")
was deprecated. In place there of, there is
a subprocess to use.
Hi Ken,
Yes: subprocess.Popen(), along with Popen.communicate(), are what you
want to look at.
For your example above, the change is relatively direct:
##############################################
import subprocess
pr = subprocess.Popen(['lpr', 'w'])
pr.communicate(month + ' ' + '\t\tLine ')
##############################################
The main difference between this and what you had earlier is that you
send all the input at once using Popen.communicate().
There's a quick-and-dirty section in the documentation for converting
from the os.popen call to the subprocess equivalents. See:
https://docs.python.org/2/library/subprocess.html#replacing-os-popen-os-popen2-os-popen3
.
Thank you for helping me get on the road here. I printed out your
response and I'll be playing with it.
Ken
