Top Forums Programming Python - store output of command to a variable Post 303007501 by atanubanerji on Friday 17th of November 2017 07:21:07 AM

Thank you very much Robin for your help.

I have to execute some action if the server is CentOS.

The server_description variable may or may not store CentOS key word among few other words. So I was thinking, if I could execute
"CentOS in server_description which would return either "True" or "False". If it is True, the python would perform some action. I have been advised to store the True or False value in another variable.

My problem is I am unable to store True or False in other variable, say, my_Check.

If I could do that, probably I could use the following -
Code:
if my_check == "True":
    do_something
else:
     do_otherthing

Could you please advice, how I can store a command's output, here, "CentOS in server_description in a variable (or any other python level command later) and use the value of the variable whenever required.
e.g.
Code:
server_description = "This is xyz abc of mno CentOS"
my_Check = "CentOS" in server_description
if my_Check == "True":
    print("This is CentOS")
else:
    print("This is NOT CentOS")

The output I am getting is "This is NOT CentOS"
CentOS 7.4 is OS version and Python 3.4.5
I could do it using shell, but I have been asked to use Python only, as the action to be performed based on the condition, if True or False, is already written in Python.
Please don't consider my objective is to print either CentOS or NOT CentOS, rather some other successfully written python code that I will be pasting in if or else section.

While testing, I found this, but not sure why it is not working...
Code:
>>> server_description = "CentOS"
>>> my_Check = "centos" in server_description
>>> my_Check
False
>>> my_Check = "CentOS" in server_description
>>> my_Check
True

XkbSetDetectableAutoRepeat(3)					   XKB FUNCTIONS				     XkbSetDetectableAutoRepeat(3)

NAME
XkbSetDetectableAutoRepeat - Sets DetectableAutoRepeat SYNOPSIS
Bool XkbSetDetectableAutoRepeat (Display *display, Bool detectable, Bool *supported_rtrn); ARGUMENTS
- display connection to X server - detectable True => set DetectableAutoRepeat - supported_rtrn backfilled True if DetectableAutoRepeat supported DESCRIPTION
Auto-repeat is the generation of multiple key events by a keyboard when the user presses a key and holds it down. Keyboard hardware and device-dependent X server software often implement auto-repeat by generating multiple KeyPress events with no intervening KeyRelease event. The standard behavior of the X server is to generate a KeyRelease event for every KeyPress event. If the keyboard hardware and device- dependent software of the X server implement auto-repeat by generating multiple KeyPress events, the device-independent part of the X server by default synthetically generates a KeyRelease event after each KeyPress event. This provides predictable behavior for X clients, but does not allow those clients to detect the fact that a key is auto-repeating. Xkb allows clients to request detectable auto-repeat. If a client requests and the server supports DetectableAutoRepeat, Xkb generates KeyRelease events only when the key is physically released. If DetectableAutoRepeat is not supported or has not been requested, the server synthesizes a KeyRelease event for each repeating KeyPress event it generates. DetectableAutoRepeat, unlike other controls, is not contained in the XkbControlsRec structure, nor can it be enabled or disabled via the EnabledControls control. Instead, query and set DetectableAutoRepeat using XkbGetDetectableAutoRepeat and XkbSetDetectableAutoRepeat. DetectableAutoRepeat is a condition that applies to all keyboard devices for a client's connection to a given X server; it cannot be selec- tively set for some devices and not for others. For this reason, none of the Xkb library functions involving DetectableAutoRepeat involve a device specifier. This request affects all keyboard activity for the requesting client only; other clients still see the expected nondetectable auto-repeat behavior, unless they have requested otherwise. XkbSetDetectableAutoRepeat sends a request to the server to set DetectableAutoRepeat on for the current client if detectable is True, and off if detectable is False; it then waits for a reply. If supported_rtrn is not NULL, XkbSetDetectableAutoRepeat backfills supported_rtrn with True if the server supports DetectableAutoRepeat, and False if it does not. XkbSetDetectableAutoRepeat returns the current state of DetectableAutoRepeat for the requesting client: True if DetectableAutoRepeat is set, and False otherwise. RETURN VALUES
True The XkbSetDetectableAutoRepeat function returns True if DetectableAutoRepeat is set. False The XkbSetDetectableAutoRepeat function returns False if DetectableAutoRepeat is not set. X Version 11 libX11 1.6.0 XkbSetDetectableAutoRepeat(3)
