Learn Python Coding (Without Udemy Courses)

July 19, 2022 / robertsgreibers / 1 Comment

It’s Roberts Greibers here. I’ll tell you about myself in just a moment.

But right now I want you to take a look at Yuliia’s Success Story video down below.

Yuliia recorded her success story right after getting hired as a Python developer in the US and this happened just after training in Python for 6 months. 🚀

Most Python courses (especially Python Udemy courses) are filled with basic Python online training material.

The mentoring method Yuliia followed is NEW and different…

It’s the ONLY type of Python training that can guarantee you’ll become a professional Python developer. 🐍

So, if the above sounds interesting to you, keep on reading, I’ll tell you the whole story of how Yuliia managed to become a Python developer in just 6 months! 👇🏻

Python XML Parse – ElementTree Reader & Parser

April 29, 2022 / robertsgreibers / 0 Comments

In this Python XML tutorial, you will learn how to use xml.etree.ElementTree package (which is one of the many Python XML parsers) to process XML response.

For this tutorial, you can use your own XML response or follow the steps below and use the one I have provided.

The Python XML parsing steps I’m about to explain and guide you through were developed alongside a refund payment integration I was working on in Django.

We’re going to explore the parsing end result for the SOAP XML response I wrote about in the previous post. The SOAP XML parsing post was written with a focus on an actual regex parsing in Python and all the steps before you get to the actual XML scheme style response.

In this post, I’m about to give you a Python XML tutorial for parsing XML schemes when you already have a decoded version of an XML response and you see the information.

The post here is about extracting specific values from the whole XML tree without using regex or any other typical Python parsing tools, but the actual xml.etree.ElementTree package (the right way)

By the way, Roberts Greibers here – in my day job, I’m working as a Python Django backend developer for a local company in Riga, Latvia, and building a white label payment gateway platform.

Over the past couple of years, I’ve gathered a lot of experience in the FinTech industry, practical knowledge of how payment systems work, how to develop, test and deploy them with minimal headache.

Of course, I can’t go into too much detail here in a single blog post, but if you want to build your own portfolio project and become a Python and Django developer, I’d suggest checking out client testimonials here and reaching out to me.

I go very deep and always explain all the steps in detail with specific videos and documents for my clients. So the post here is just a small example of how I could help you out.

Also, I always answer all client questions along the way.. but enough of talking, let’s get into the code.

Parsing SOAP XML Response In Python

March 16, 2022 / robertsgreibers / 0 Comments

In this tutorial, you will learn how to decode and parse a large SOAP XML response with Python and regular expression, essentially the goal here was to build a Python function to get rid of manually decoding SOAP XML response over and over again.

The Python code I’m about to explain and show you was developed as a part of refund payment integration done in Python and Django.

We’re going to take a look at an encoded SOAP XML response stdout saved in a text file.

I saved this SOAP response output when I was in a process of developing a payment integration feature for a local bank here in Riga, Latvia, along the way I realized it’s going to be a great learning experience for anyone else who’s going to search for a similar solution on Google.

I’ve discussed similar text file parsing in Python situations before here on the blog, but the difference here is that this one is way more complicated and involves a bit more decoding and text manipulation as well as extensive knowledge on regex pattern matching.

Definitely a good Python regular expression practice, even for advanced Python developers.

Currently, I’m working as a Python Django backend developer (Roberts Greibers) for a local company here in Riga, Latvia – building a white-label payment gateway platform, you can find more about my experience on my Linkedin profile

Give me a follow on Linkedin or send me a DM if you have any questions.

One of the recent payment integration flows I needed to develop was for a refund payment. Refund payments were supposed to work for multiple banks through one gateway system for this particular client and brand.

The whole refund payment flow is way more complicated and would take me weeks to write up and explain here on the blog so I’m gonna share a small portion of what actually was very interesting to work on – parsing decoded SOAP XML response with regular expression in Python.

I go deeper explaining features you can develop for your Python and Django portfolio if you’re working personally with me in one on one Zoom calls (click here to see an example of a LIVE Zoom call). I personally will guide you through the development of each feature and answer all your questions along the way.

This is what we’re working on with my most successful mentoring clients.

So if the above sounds interesting, let’s get started!

Django: How Painful And Difficult It Is

February 28, 2022 / robertsgreibers / 0 Comments

Hello there!

Welcome back – or nice to have you for the first time!

Roberts Greibers here and in this post, I want to share with you how painful and difficult the Django framework is and how much Python is required for a Django developer position – this is especially important for Python beginners who are interested in becoming a Django developer.

If you’re reading this post…

And you’re seriously considering becoming a Python/Django developer

Starting from scratch and getting your very first Python/Django DEV job can make you feel a little lost -“Where to actually start?”

All these doubtful questions can come to your mind and you can start to feel unsure about yourself

If that sounds familiar, keep reading – this post is exactly for YOU!

My 3 Unit Tests Tips In Python Django (REALLY Important!)

February 4, 2022 / robertsgreibers / 0 Comments

Good morning! Welcome back, Roberts Greibers here, and in this post, I want to talk about my three unit tests tips that have allowed me to get into writing unit tests in Python Django way faster, in a way more scalable way.

These are unit tests tips that you will definitely need!

Because when it comes to building a Python Django project you can’t build anything without having proper test coverage.

If you like the idea of becoming a Python Django developer, building your own Django projects, writing professional code which is also covered with unit tests – this post is exactly for YOU!

These are tips that I literally use every day when I’m working on new features in Python Django and I wish I knew about them when I was just a beginner Python developer.

I’ve been working professionally as a Python developer for more than 5 years now – and for the past couple of years, I’ve been working in the fintech industry, building a white label payment gateway product for a local company (ourspell.com) in Riga, Latvia.

You can read more about my experience on my Linkedin here.

I’m also helping junior developers who are at beginning of their careers (see the LIVE mentoring call here) to take a shortcut and basically use my code examples, techniques I have collected over the years and apply them to their own projects to get their first Python Django job opportunities.

In the end, what I’m about to give you here in this post is just a small portion of what I share with my clients.

But this will definitely help you write better Python scripts if you’re serious about becoming a Python/Django developer.

Wait For Elements In Python Selenium (5 Powerful Examples)

January 23, 2022 / robertsgreibers / 0 Comments

Alright, welcome back to the blog, Roberts Greibers here, and in this post, I want to talk about five powerful examples you can use in Python Selenium to wait for elements when working on automation projects.

Whether you’re just getting started as a Python developer, or you are already in the industry as a test automation engineer and looking for more effective ways in Python selenium to wait for element – this post is for you!

These are not just things that I’ve just randomly come up with!

These are not just theoretical concepts!

These are code examples in Python selenium to wait for element that I have saved in my notes since a long time ago and I literally used them back when I used to work on test automation projects.

The code examples I’m about to show you are few of the best ways in Python selenium to wait for element that allowed me to improve the speed of my test automation scripts!

I’m going to show you a code to:

wait for element to be found (any situation)
wait for element to be visible
wait for element to be clickable
wait for element to load
wait for element to be displayed

… which one to use depends on a specific situation you’re working on. But I can assure you, in the end, these code examples led me to write more advanced Selenium automation test cases.

And NO! It’s not going to be about using just the typical time.sleep(1) solution. I’ll show you where it’s appropriate to use time.sleep(1) and I’ll show you the best ways I know in Python Selenium to wait for element.

import time

time.sleep(1)

I’ve been working professionally as a Python developer for more than 5 years – a part of it was as a quality assurance engineer where I worked with Python and selenium framework a lot.

Eventually, I became a Python/Django developer (see my Linkedin here) and now I’m also helping relatively new engineers (quality assurance engineers, analysts, etc.) to become Python developers. (see a cut from a LIVE mentoring call)

If you like the idea of becoming a Python developer, learning about Selenium framework tricks, and eventually maybe even becoming a Django developer, then this post is for you!

Python Training: Why You Shouldn’t Attend It (3 Important Reasons)

January 11, 2022 / robertsgreibers / 0 Comments

Good afternoon, Roberts Greibers here, and in this post I’m going to expose the awful truth about python training in NYC (New York City) and also all over the world.

I’ve been working professionally as a Python developer for more than 5 years and now (see my Linkedin here) I’m also helping people who are in a similar position I was when I first started – to become Python developers. (see a cut from a LIVE mentoring call)

Ever since I started to lean more into the field of helping people, I realized how many horror stories are out there about a common Python training course.

Every now and then I hear a new story, a new shocking price of a training course, and now it’s no surprise to me that there is a lack of good Python developers out there.

I used to be a quality assurance engineer (manual tester) – testing website projects and apps so I totally get that a lot of people want to move away from their current job and get into more profitable positions like becoming a Python/Django developer.

Maybe you’re somebody who wants to become a Python developer, be more independent, more free from a typical 9-5 job, maybe even work remotely from anywhere in the world, and have a higher income than what you’re used to.

So if that’s you, I want to give you a little bit of a counterbalance to all the wild claims that all these Python training courses out there are currently making.

5 Secret Debugging Tools For Python And Django

January 7, 2022 / robertsgreibers / 0 Comments

Alright, Roberts Greibers here with another experience-based Python post.

I’ve been working professionally as a Python developer for more than 5 years and now I’m also helping people who are at the start of their careers (or in a similar position I was in) to become Python developers.

I used to be a quality assurance engineer – manually tested website projects and mobile apps. (iOS, Android)

So I totally get how it is when you want to move away from your current role and get into a more profitable position, for example, become a Python/Django developer.

What I’m about to show you in this post are five of the most important tools I used and my clients are using now (see a cut from a LIVE Zoom video call below) that made me look like a senior Python developer even though I was just starting to learn Python.

Amazon Scraping In Python Selenium

December 30, 2021 / robertsgreibers / 0 Comments

Follow the steps below:

Scraping data from any kind of website with Python can be exciting and challenging at the same time. Also, you can learn a lot about development and writing simple scripts – practice Python’s fundamentals.

More than 5 years ago, when I first started to get to know what Python is capable of – the very first thing I wanted to learn was how to automate browser actions – open websites, click on buttons, enter text into input fields, etc.

Back then I was learning how to automate facebook.com

Within the following steps, you will learn how to automate scraping data from amazon.com from A-Z.

I’ve prepared steps with everything you need to do in order to be able to fully automate the process and gather data for up to 100 products in less than a minute.

With the provided code you’ll have a good base for starting the Amazon website automation and you’ll be able to expand and extend my code to whatever your goals are.

Follow the steps below.

Python Regex Groups, Match and Search

November 24, 2021 / robertsgreibers / 5 Comments

Hey, Roberts Greibers here. I’ll give you a brief intro about my 7-year experience as a Python developer down the line – later in this post.

But now I want you to scroll a bit more and dive right into Python regex groups and the Python regex example I’ve greatly detailed below.

The following regex Python example is going to show you.. ⚠️

What actually is import re in Python and how you can use it!
How to THINK and come up with your own Python regex patterns
A real-life Python regex example (sent in by a reader of this blog post)

If you’ve been Google searching for Python re examples, you’ve found the RIGHT place!

Most regular expression Python examples you’ll find online are very theoretical, showing you just the concept of a regex capturing group.. but they don’t tell you how to THINK in order to come up with your own solutions – your own regex patterns.

In this post, I’ll take a real Python regex situation and explain what fundamental steps I take to come up with a solution. 🚀

And if you really think about it…

It’s the ONLY way for you to truly understand regex Python examples and use them for your benefit. You have to understand the fundamental process behind solving a Python problem.

So, if getting deeper into a real regular expression Python example sounds interesting to you – keep on reading!

I’m explaining the whole story of how I came to the following situation in Python where regex capture group was part of the solution down below! 👇🏻
