✔ Why would you take this course?

Hi! My name is Mihai. I've been a Network Engineer since 2008, having the privilege of working for 3 major corporations and configuring, maintaining and testing multi-vendor network environments. At the same time, I managed to obtain several well-known certifications, such as CCNA, CCDA, JNCIA and CCNP, which complemented the skills I was getting from my job and increased the number of job offers I was receiving to my LinkedIn inbox.

But the thing that simply jumpstarted my career was learning the Python programming language and implementing it in some of my daily tasks and processes. I've been a self-taught guy for most of my adult life and, since I lacked the time to read endless, boring programming books, I chose to learn by watching video tutorials and "getting my hands dirty" with code. Unfortunately, at that time I was unable to find a complete, coherent programming course for network engineers, so I had to put together various pieces of information scattered across Google and YouTube.

Almost two years later, after I had the chance to practice my new Python skills intensively, performing various tasks on network devices and automating hundreds of network tests, I decided to create this course for you – the network professional who knows that getting a certification just isn't enough anymore in today's job market. The ability to write scripts and automate certain tasks is one of the primary skills that the big employers are looking for.

This course simply enables you to save time and efforts whilst acquiring these in-demand skills and upgrading your career.

Join thousands of successful network engineers who decided to learn Python network programming using my 100% hands-on courses!

Without further ado, I'll let you read more about the contents of this course down below and I'll hopefully see you in the first lecture.

• Multiple hours of Python 3 content designed for Network Engineers
• Full Python 3 applications, code and notebooks are included
• Downloadable Python 3 Beginner's Cheat Sheet is included
• Over 70.000 satisfied students across several e-learning platforms

• What others have to say about my Python courses?

Before you read what I have to say, see what my students are saying about my courses:

"What an incredible value and learning experience!" by Sean A.

"Excellent material. Kudos to a great instructor with a vast level of creativity." by Anthony W.

"I can say this man is going on smoothly and perfectly, explaining in the most empirical/foundational way." by Kolapo A.

✔ What's this course all about?

Python Network Programming (using Python version 3.8) course aimed exclusively at network professionals / engineers / admins.

During this course you will build 5 very useful network tools:

• Introduction
• Setting Up the Working Environment
• Application #1: Read SNMPv3 objects with Python 3
• Application #2: Build a Basic NMAP Tool with Python 3
• Application #3: Build a Rogue DHCP Server Discovery Tool with Python 3
• Application #4: Filter and Monitor LLDP Log Messages with Python 3
• Application #5: Build an OSPF Network Discovery Tool with Python 3
• Final Section

Equipped with working files, cheat sheets and Python code samples, you will be able to work alongside me on each lecture and each application. I will provide the full code for each application, so you can save time and start coding and testing on the spot.

✔ What others have to say about my courses?

"I have been programming since 1978 and wanted to learn python. I have had no java or OOP experience, and I tried several 'paper' tutorials but got little out of them. The first part of this course is a steady walk through the Python language at just the right speed. The instructor seems to touch all the basis in a logical and methodical way while providing examples and explanations. I can only conclude the instructor is a professional educator who spent considerable time structuring and organizing the course. The result is evident. THIS IS A GREAT WAY TO LEARN PYTHON!" by Larry Laswell

"I've tried learning from the books & multiple videos – most were too basic to make a practical app. Some books were too thick and made me sleep. But still none of the materials had the perfect balance like this course where all the basics were covered, instructions were concise, and Mihai walks you through how to create 7 practical apps step by step. I've also tried reading some advanced python book which didn't make sense because it was too advanced. Let me tell you, this is hands down "that course that takes you up to beyond the basics" to bridge you to the advance topics. Right now I'm hitting the advanced topics and it finally makes sense…" by Joon Park

"Usually I'm not doing courses review but this time I will make an exception. During time I took a lot of trainings but very few provided by Udemy proved as having the right approach in teaching the audience. I will mark this one as being one of my personal top three best trainings as content's quality, technical explanations, and additional learning materials perspective. Long story short this course is a very simple, straight forward way of learning Python for managing IT networks." by Johnny Stanescu

"This is a great course for network engineers who would like to start automating their tasks. Geared towards beginners, this course teaches the fundamentals of programming and applying those concepts to networking. There is a lot of fluff about python on the internet, however the instructor managed to put together the necessary information to start automating the network. A working knowledge of TCP/IP is needed to get the most out of this course. Should you understand every lecture, you will be ready to start writing your own scripts according to your needs. In particular, I loved the use of scapy, an amazing tool which should be in the arsenal of anyone working with TCP/IP." by Costin-Alin Neacsu

"I've seen the blueprint and some demo videos and I was convinced right away. Without a doubt, it's one of the best trainings a network engineer can have. It gives you actual valuable and marketable skills that you can use in your daily job. Mihai explains the topics really well, with practical examples making it a fun way to learn. Highly recommended." by Vlad Vlaicu
