Python for Automation Course Online

Although it is less talked about, automation might be the single biggest payoff for learning Python. By "automation," I mean code that directly replaces human labor. A computer program, in other words, that finishes tasks you normally do by hand.

The Upside of Automation

The personal benefits of automation are twofold: your work is less tedious, and your day is more productive. Let’s say that, as an example, you need to build a report every month. Being able to automate that process means less typing for you, but also a faster delivery to everyone who reads your report. That’s a win-win scenario.

On a larger scale, some people have managed to automate their entire job. Journalists have called this strategy "self-automation" or "auto-automation." Success means that you can go into work, run an automation script, and spend the rest of the day enjoying Reddit and YouTube. This raises new questions, of course. Are you obligated to tell your boss? Does goofing off all day really make you happy? One thing should be clear, though: if code can do your work, you’re wasting time doing it by hand.

Automation can scale to the size of an entire business as well. The websites NomadList and RemoteOK cater to tech workers living abroad and together bring in a million dollars a year in revenue. Despite supporting thousands of users, both websites are run by a single programmer named Pieter Levels. How is such a thing possible? Levels uses over 200 automated scripts (also known as "cron jobs") to handle most of the maintenance. 

Why Automation Is Good for Beginners

Perhaps most surprisingly, automation is relatively easy compared to other uses for Python. Data science and web development, the most popular uses for Python, involve lots of user data and abstract concepts. Automation is easier for beginners to pick up because these sources of difficulty are typically not necessary.

User data causes problems because it is unpredictable. A data scientist, for example, can easily spend a hundred hours per year just correcting typos in their data. When data is entered by hand, there are no guarantees. Human error is also an issue for web developers, but even worse is input that is intentional and malicious. In a SQL injection attack, a user enters code into a normal form field to gain control of the website’s database. An attack like this can bring down your website and expose sensitive data. Since automation involves little to no human input, there are fewer risks like these to consider.

Since automation scripts mimic human behavior, it is also more concrete and easier to understand. You’re typically simulating actions you’ve already done by hand rather than diving into new technical concepts. Your code might move files around, enter text into a field, or send an email. These are all things you, as a human, have done before. By contrast, there is no human equivalent of what servers and databases do in web development. These are entirely new concepts! This is even more true in data science, which involves higher-level math and statistics. To get started with automation, on the other hand, you don’t need as many abstract concepts because you are just simulating things you have already done.

Automation Projects

If you are excited about getting started with automation, there are several types of projects you could look into. Here are a few ideas:

1. Web scraping: This term refers to pulling data from websites through code rather than by hand. Do you search the same sites repeatedly, looking for deals? Or do you grab quarterly earnings from the same site, over and over? These are the kinds of tasks you can automate with web scraping.

The easiest way to get started with web scraping is through Selenium. Selenium uses an internet browser the same way you do, so it is easy to translate your usual actions, like clicking the mouse or typing in text, into your Python code.

2. Emails and Text Messages: It’s often useful to send an email or text message automatically, using your Python code. If you find a great deal online through web scraping, for instance, how do you alert yourself in time? Automated text messages are also useful for sending scheduled reminders.

The easiest package for sending email is Yagmail, which is specifically designed to work with Gmail accounts. For text messages, you can either use the email-to-text gateway provided by your phone carrier or a service called Twilio.

3. Testing: If you have a website, automation can give you peace of mind from worrying whether your site is up and functioning properly. At the most basic level, you can have a Selenium script running every few minutes to validate that your home page loads. More advanced testing might make sure that other features, such as important forms and videos, are also working as designed.
