Python Monthly 💻🐍 July 2020

Andrei Neagoie

8th issue! **If you missed the previous ones, you can read the previous issues of the Python Monthly newsletter here.

If it’s your first time here… (otherwise, skip this part)

Being a Python developer is a fantastic career option. Python is now the most popular language with lots of growing job demand (especially in the fields of Web, Data Science and Machine Learning). You have many job opportunities, you can work around the world, and you get to solve hard problems. One thing that is hard, however, is staying up to date with the constantly evolving ecosystem. You want to be a top-performing python developer, coder, programmer, software developer, but you don’t have time to select from hundreds of articles, videos and podcasts each day.

This monthly newsletter is focused on keeping you up to date with the industry, keeping your skills sharp, without wasting your valuable time. I will be sharing the most important articles, podcasts and videos of the month. Think Tim Ferriss and the Pareto Principle (80/20 rule) meeting the Software Development world. What’s the 20% that will get you 80% of the results?

What you missed in July as a Python Developer…


Python reduce() 🧿

The reduce function is one of the most useful tools you have as a programmer. Although it can be hard to understand at times, by using the reduce function you can implement a lot of useful things like map(), filter() and much much more. Here is a tutorial to show you its functional powers.

Subprocess Genie ⛲️

Python Subprocess just sounds like something cool you would hear a hacker on TV say. However, this is actually a useful skill and something you can do quite easily in Python to take advantage of extra CPU power or to run an App inside of another app. Here is how to do it.

Distributed Python With Fiber 🎳

One of the biggest changes lately in the Python landscape is the move towards distributed computing to take advantage of the power of multiple machines. However, this is a hard thing to do and many tools and libraries are being developed to make distributed computing easier with Python. One of the new kids on the block is Fiber from Uber. Just read the introduction part of this article if you want to get an overview of the problem it solves.

Python Quiz 📋

Pop quiz for you: What is the most efficient way to remove half of the duplicate items in a list. For example to go from l = [1, 8, 8, 8, 1, 3, 3, 8] to k=[1,8,8,3]. Try to figure it out on your own before you check out the solution here.

Everything About OOP 🤹‍♀️

Object Oriented Programming sometimes gets a bad rep, but it is a very useful programming paradigm that has stood the test of time. Here is a tutorial on how to do OOP and also how to make your code cleaner and more efficient using this programming paradigm.

Weekend Project Idea 🎏

This is a project that will surely wow your future employers. Create an application to find restaurants with the help of food images you have. You will also learn how to work with IBM Watson for Visual Recognition and use location services for maps and location analytics. Here is the project walkthrough.

New Python Extension On VS Code 🔋

Another feature rich VS Code extension when you are writing Python. There are lots of these around, but this looks to be a promising one for one of the most popular editors.

YouTube Data Analysis 🎥

A great overview of how to collect and analyze data to produce meaningful insights. Something you can do really well within the Python ecosystem. This is also a fun project for you to follow along and discover new insights. The big takeaway? If you want your YouTube video to trend, make sure you have a person in the thumbnail.

All About Python Memory 🤖

Two articles to really dive deep into how memory management works in Python.

  1. How Python function calls can increase your memory usage
  2. How NumPy helps numbers memory in Python. By the way, here is a massive free tutorial on NumPy. Why should you care? It's one of the most used python libraries in the world.

PEP622 - Pattern Matching 🎰

New PEP proposal brings Python in-line with many other modern programming languages, like Haskell, OCaml, and Rust. It is a useful feature that will allow you to search/match strings.

Favourite Data Structure 🥇

What is your favourite Data Structure? Wait, you don't have one? Don't look at me with those crazy eyes. Everyone should have a favourite data structure. Mine is a Hash Table or in the case of Python, Dictionaries. Here is why it's such a useful tool in any programming language arsenal.

Python Malware On The Rise 🦂

"The vast majority of serious malware over the past 30 years has been written in Assembly or compiled languages such as C, C++, and Delphi. However, ever-increasing over the past decade, a large amount of malware has been written in interpreted languages, such as Python. The low barrier to entry, ease of use, rapid development process, and massive library collection has made Python attractive for millions of developers - including malware authors." I guess it's part of being the popular language on the block. Check out the full analysis here.

News Around the World 🗺

  • Unsecured MongoDB and Elastic Search databases are a common thing. This is because they have unsecured defaults and a programmer/administrator needs to enable those safety features. Well, somebody created a program to delete all those unsafe instances to force people to secure these databases better.
  • Australia is making Facebook and Google pay for the news that they display on their search results from Australian companies. An interesting move that may effect what other countries do with news in the future.

Big Tech News 🏢

  • Apple, Google, Facebook, and Amazon are all getting questioned for anti trust. Keep an eye on this.
  • Twitter got hacked big time this month through some silly security practices that they had internally. The hackers? A bunch of teenagers.
  • An interesting article on why this company isn't interested in implementing Sign in With Apple. But the big news out of Apple this month was their move to AMD chips for their laptops. "We’re about to enter an exciting, messy transition. Not only will Apple Silicon make better Macs, it will force Microsoft to polish its Windows on ARM act, both hardware and software. In turn, this will cause PC OEMs to reconsider their allegiance to x86 silicon… and that will have serious consequences for the old Wintel partnership." Check out the explanation of what this means here.
  • Barclays was caught using the internet archive as a CDN (bad because they make enough money to not use a non profit's servers for free).
  • Facebook's SDK for iOS crashed a bunch of apps (a lot of big apps) again and people were not happy.
  • Do you feel like you are unqualified for a job? IBM is hiring people with 12+ years of Kubernetes experience. Fun fact, K8s came out in 2014.
  • Google is investing $10 billion in India. Lots of big companies moving assets into the booming Indian tech scene lately. Speaking of Google, they are now doing online certificate programs and offering 100,000 scholarships. This is a positive trend that hopefully more and more companies will adopt (most people in the world can't afford to pay $100,000 for a fancy CS Degree, nor do you need it to be a great programmer). Maybe soon Google will announce their scholarship program for ZTM Academy Memberships 😁!

Completely useless to your career but still great 🙃

You can now buy a Boston Dynamics dog robot and program it yourself. Guess what language? That's right, Python. Guess how much it costs? Only $74,500.

Do you know what Quine is? 99.99% of people don't. But you can be part of the select few that can explain it and pretend like you're a genius. Self Replicating Python Code.

Best Resource of the Month 🥽

A higher level of abstraction. We hear this phrase quite often in our industry. Do you fully understand it? What exactly is abstraction and why is it a useful concept when it comes to programming? Can abstractions be good and bad? This was my favourite article this month discussing this very important topic. Enjoy the read.

Ok, I have to share 2 things this month that I loved because this one is just as good. The takeaway? Write code that is easy to delete.

I lied. There are 3 articles for this month. It kind of ruins the whole point of this section, but all 3 of these articles are tied for the top spot this month. What should you do to succeed during a technical interview? This is one of the best pieces I have read on the topic.

Bonus Resource: Python Cheat Sheet 📑

Since we're best friends by now, you probably already know about this free Python Cheat Sheet. But just in case, it's a handy little page to bookmark (or you can download it as a PDF) for both beginners and experts.
