After having a long journey to the CCNP R/S earned in October, and beginning higher R/S studies along with tons of DevNet topics, I've decided its time for a break to deal with some life events that are weighing on my mind and distracting me from studies. My list of priorities during my break time: … Continue reading OOO – Need a rest and reset from studies!
It is Python Time! However, the CCNP R/S Grind notes are forever here! As you have probably noticed I took small break to explore some other topics that I've always just wanted to know outside of the CCNP Blueprint (MPLS / VRF / DMVPN in depth), and I have now made a full pivot towards … Continue reading Python / Linux Studies – CCNP R/S Notes still available, but currently studying DevNet, currently Python 3.x and Linux!
I just absolutely love this graphic, perfect representation of the Cisco struggle! Moving forward I will be posting non-Cert related technologies! Now to that I have earned my CCNP R/S, I've decided to take a breather with some lighter topics such as MPLS Layer 3 VPNs, which apparently are part of the CCIE R/S Syllabus. … Continue reading Though I have earned my CCNP R/S, the Grind never stops my friends, I am just getting started!!! 🙂
On April 5th 2016 (4/5/2016), I made my first post to this blog, and today on October 10th 2019 (10/10/2019) I have passed my final CCNP Exam the TSHOOT 300-135 🙂 Along the way I have hit many major life events that could very well have stopped my progress, gave me a reason to put … Continue reading CCNP R/S Certified – 1,283 days and 286 posts on Loopedback.com later! 🙂
It's been a long couple of years of medical issues that have stopped me from actually taking the exam, but have studied the material over and over, and finally took it today and passed it on the first attempt. I have to say that all of the questions on the exam were absolutely outside what … Continue reading 300-115 SWITCH Exam Crushed! Tips on how I navigated this mentally exhaustive exam for the Pass grade!
Finally after my first two Failed attempts at the ROUTE exam, I have finally FINALLY passed it!!! I have to say I took the first fail as a learning experience, but after some intense brushing up on all topics and failing again, I didn't reschedule a 3rd attempt as I didn't think I wanted to … Continue reading 3 must know tactics to get a “Pass” score on exam day, as can be seen here on my ROUTE exam score printout (finally)! 😀
Above is a program I will walk through at the bottom of this shorter post, as this is not a robust review of all Libraries / Modules importing just yet. With that I will get right into it! What is a Library / Module in Python, and what is Built-in VS Imported? The functions / … Continue reading Python – Libraries / Modules / Functions, Built-in VS Imported, and a demo of importing libraries into a Py 3 program!
In continuing through Automating the Boring Stuff book, I thought posting some demonstrations of Loops and how to program them to avoid infinite program loops would be a critical concept to get documented to reflect on. First concept of Loops, using the "while" keyword rather than "if" statements While is a loop statement / expression … Continue reading Python – Configuring “While” and “For” Loop Types, “Continue” and “Break” statements, and range function reviewed!
Important Note - The above flow chart is not something I would imagine is a best practice for a program to keep returning back to the original Conditional "if" every time the program gets input, though I wanted to just throw up a general example. The above Flow Chart is a very small example of … Continue reading Python – Creating a flow chart using Boolean logic to produce a result, rather than running every line of Python Code!
I probably won't use all here, but I will use as many as possible, to get demo's for all these concepts out of the way - This is all thanks to one following Google Play App: https://play.google.com/store/apps/details?id=com.vrpmeone.LearnPython&hl=en_US If you are a beginner download this! I enjoy my "Automate the boring stuff for more expansive reading, … Continue reading Python – A quick look at some of these Data Sets in IDLE Console, and taking a first look at the Splice Operator : !
In the spirit of the SuperBowl tomorrow and Tax Season here in the US, I thought I'd follow up / end my review of Mathematical gotchas in Python coding, and how to make a practical application (at the very bottom) that I whipped up off the top of my head as mock Tax calculator but … Continue reading Python – Explanation of Mathematical Literals, Concatenation, and demonstrating with Pizza and Taxes!
This is a program from "Automate the boring stuff" that really turned on the light on a lot of concepts for I believe Python 3.x specific syntax, and just in general (stuff also in 2.7). I'll run through this quick as getting on the lab was not easy tonight, but I want to nail these … Continue reading Python – Demonstrating a simple Input/Output program in VSC, and how to use this info to practice until perfect!
I had to pause my CBT Nuggets studies as it was 2.7 being taught, and once I hit lists and loops the syntax was just too different to keep going, so I will be kind of restarting with a few different materials including the book shown here - Automating the boring stuff! I highly encourage … Continue reading Python – Taking a look at Python 3 Integer Operators, and PEMDAS refresher for Order of Operation in math equations!
Above is the if / elif / else in action, but there is a lot of vocab to know about along the way, along with some new operators and how they work! To jump right into some Terminology for these Conditionals! Being that programs are "Logically Malleable" this allows them to use what are called … Continue reading Python – Review of Conditionals “if” / “else” / “elif”, intro to new operators, and important vocab review of two terms!
I waited until I got into this course to grab a screen snip for an image, and this has been a LinkedIn favorite, so I'll go with this as the cover photo of the day 🙂 Input and Output and where its executed at what times Input and Output at its highest level is allowing … Continue reading Python – Input and Output functions, where a program can accept input to produce dynamic output based on input!
This is as straight forward of a variable demo as you can get with Python, X + Y = Z! Variables in Interactive Mode (on the Terminal executing code) is cached in a sort of memory until saved to a .py file, however if you do not save this in 'Interactive Mode' in a Terminal … Continue reading Python – Variables overview, concepts, terminology, and making some Python programs to demonstrate Variables!
The very first print in a long journey of printing phrases, automating tasks, and everything between - Hello, Python! This window is a demo of Python "IDLE" terminal that can be downloaded from python.org for "Interactive mode" or immediate code execution like the Hello World print code seen above! This is going to be a … Continue reading Python – Intro to different types of languages, then get into the nuts and bolts of Python basics!
RESTCONF is the cousin of NETCONF which both use YANG Data Modeling to talk, although while I know NETCONF prefers XML as its choice of encoding data to communicate and SSHv2 via TCP Port 830 to communicate, I assume that is where we will see some differences between RESTCONF and NETCONF protocols. With that lets … Continue reading ENAUTO – RESTful APIs and RESTCONF completely reviewed, some much needed comparison to NETCONF, and configs!
A nice Cisco 9k for the low price of $65k - $75k for your lab! I was actually looking at Nexus 2k switches around the net for like $100, and started talking myself into rebuilding a new lab for Automation with Physical switches, but had to fight the urge to start getting 5 lbs boxes … Continue reading ENAUTO – NETCONF Deployment review, some of the requirements for deploying, and commands for deployment as well!
