[Tutor] array input from keyboard
I need to accept input from the user then store in an array/list. This is my
1st python script.
#!/usr/bin/env python
# Derek Smith
# 09/2017
# accept volumes for TSM for tape mgmt.
import os
import sys
nput1 = ""
nput2 = ""
nput1 = input("\nIs your input 'file' based or 'cli' based? ")
if nput1 == "file" :
nput2 = input("Please provide your input file? ")
nput2 = nput2.lower()
print (nput2)
fh = open(nput2,"r")
for ln in fh:
ln = ln.rstrip()
os.system("/usr/bin/dsmadmc -id=dereksmith -password=x -dataonly=yes
move drm %s" %ln, "tost=onsiter")
os.system("/usr/bin/dsmadmc -id=dereksmith -password=x -dataonly=yes
move drm %s" %ln, "wherest=vaultr tost=onsiter")
elif nput1 == "cli" :
vols = []
vols = input("Please enter your volume ids, comma delimited? ")
vols = vols.upper()
for vols in vols :
vols = vols.rstrip()
print("/usr/bin/dsmadmc -id=dereksmith -password=dereksmith
-dataonly=yes move drm %s" %vols, "tost=onsiter")
elif
print ("Incorrect input, exiting.")
sys.exit(99)
__OUTPUT__
# python tsm_moveVR_tonsiter.py
Is your input 'file' based or 'cli' based? cli
Please enter your volume ids, comma delimited? r20344l5,r20355l5
/usr/bin/dsmadmc -id=dereksmith -password=x -dataonly=yes move drm R
tost=onsiter
/usr/bin/dsmadmc -id=dereksmith -password=x -dataonly=yes move drm 2
tost=onsiter
/usr/bin/dsmadmc -id=dereksmith -password=x -dataonly=yes move drm 0
tost=onsiter
/usr/bin/dsmadmc -id=dereksmith -password=x -dataonly=yes move drm 3
tost=onsiter
/usr/bin/dsmadmc -id=dereksmith -password=x -dataonly=yes move drm 4 tost=onsite
...
...
...
Its printing each element per line. I have tried various changes, read online
help but gave up looking.
I need it to print as below:
/usr/bin/dsmadmc -id=dereksmith -password=x -dataonly=yes move drm R20344L5
tost=onsiter
/usr/bin/dsmadmc -id=dereksmith -password=x -dataonly=yes move drm R20355L5
tost=onsiter
Thank you!!

[Tutor] pip install of subprocess module
Hi All, Thank for the recent replies. I want to use the subprocess.run module b/c per the docs os.system is antiquated and cannot use more than 1 arg in 3.6. Why am I doing wrong below? Also couldn't I just copy and paste the subprocess code from github and create a file, but then how do I tell python this is a new module called os.system since this py file requires os.system and os.spawn* I am on AIX 7.1, python 3.6.2, pip 9.0.1 Thx agn! # pip install git+https://github.com/python/cpython/blob/3.6/Lib/subprocess.py -vvv Collecting git+https://github.com/python/cpython/blob/3.6/Lib/subprocess.py Cloning https://github.com/python/cpython/blob/3.6/Lib/subprocess.py to /tmp/pip-bw8rryo9-build Running command git clone -q https://github.com/python/cpython/blob/3.6/Lib/subprocess.py /tmp/pip-bw8rryo9-build remote: Not Found fatal: repository 'https://github.com/python/cpython/blob/3.6/Lib/subprocess.py/' not found Cleaning up...

[Tutor] subprocess check_output
Why does python output this b and newline characters and how can I may it return just what I need, the number 8 w/no special characters? See below. I tried str(scratch), but no go, still prints that garbage. #!/bin/env python3 cmdstr= "/usr/bin/dsmadmc" id = "-id=dereksmith" pw = "-password=" do= "-dataonly=yes" from subprocess import check_output scratch = check_output( [ cmdstr, id, pw, do, "select", "count(*)", "from", "libvolumes", "where", "status='Scratch'", "and", "library_name='TS3200'" ] ) print (scratch) __OUTPUT__ # ./ts3200_scratchcount_check.py email sent successfully b' 8\n' Thx!!

[Tutor] Fwd: print a for loop system call
Sent from my iPhone
Begin forwarded message:
From: Derek Smith

Subject: print a for loop system call
Why does A work but B does not?
#!/usr/bin/env python3
import os
import sys
from subprocess import Popen, PIPE
pipe = Popen('lsdev -c tape', shell=True, stdout=PIPE)
for dev in pipe.stdout :
print ( dev.strip().split()[0].decode() )## A ##
# print ( dev.strip().split().decode()[0] ) ## B ##
And if I try to store in an array using
rmts = [ dev.strip().split()[0].decode() ]
it only stores the last line when there are over 100 lines.
Sample line looks like
rmt144 Available 04-T1-01 LTO Ultrium Tape Drive (FCP)
thank you!
