Beginner Series: Python Tutorial
Python differs from many languages because it is one of the few that is easy to learn and easy to understand.
Many consider Ruby a great place to start, like Python, yet the latter has a four-year head start. This means that it has a big foothold in the enterprise world, and it’s much more popular with C developers. This is because it’s easy to crossover between the two languages.
Both Ruby and Python share a significant amount of growth in the job market, so choosing either language would be beneficial in terms of a career. PHP is also used often though the application of the language is different.
Ultimately, it comes down to what type of content you will be developing, as each language has its niche.
What Are These Languages Used For?
The best way to understand how Python differs is to compare it to similar languages like Ruby and PHP and explain what each are used for.
PHP is a server scripting language primarily meant for the development of dynamic and interactive websites. It is ideal for creating HTML content, and can be used to build anything from a simple blog to a huge, corporate style website.

Python is a high-level, object-oriented general-purpose language, that is versatile and can be used for just about anything. It is most often used in the development of web and mobile applications, website crawlers, indexers, daemons, and desktop GUI apps. Though, it is not confined to just those purposes.
Ruby is a high-level, object-oriented language that is used during the development of web application and data entities; it exists to take the focus away from query tasks. Ruby is most famous for its dynamic type system which performs type checking during runtime. It also features automatic memory management, which is something that a lot of languages don’t offer.
Out of the three, Python is best for newbie coders. Programmers and developers often recommend using it because it employs a syntax that is easy to read.
In comparison, Ruby is better suited for programmers that have experience with other languages. PHP, on the other hand, is ideal for developers who are used to working with C languages yet want something more modern.
They all have their place in the development world, as you can see from the descriptions.
Which Companies Use PHP?
PHP was created for web development and the production of dynamic web pages. Brands that use PHP to power their products include:
Which Companies Use Python?
Python was created with an emphasis on productivity, readability, and ease of use. Brands that use Python to power their products include:
- Yahoo! Map
Which Companies Use Ruby?
Ruby was created specifically for programmers, and because of this, many find developing with the language to be fun and flexible. Brands that use Ruby to power their products include:
What is the Best Language to Learn?
It doesn’t matter who you ask, the answer to this question will always be the same.
There is no “best” in the world of programming because each language serves a purpose. To make it even more confusing, with the three languages discussed here, you can do just about anything as they’re all general purpose languages.
There is no right or wrong answer.
Also, there are frameworks available for each one of these languages, and they simplify the development process even more.
PHP has several content management systems like WordPress, Drupal, and Joomla. Python has Django and CherryPy. While Ruby has Rails or Ruby on Rails.
You can’t go wrong with any of them.
Next, we’re going to explain How to Setup the Python Development Environment.

I was looking for a well-known CMS (Content Management System) that I could easily run in a Docker container as a target for information security reconnaissance tools, such as WhatWeb.
I found an official Docker image for Joomla, a CMS that I had used previously some years ago: https://hub.docker.com/_/joomla
Using a backend MySQL database on localhost
I had some problems running it at first. I tried to set up a local MariaDB/MySQL database and have the Joomla container communicate directly with the underlying host:
That didn’t work. The Joomla container crashed shortly after starting. When I looked at the container logs using the following command:
I found the same error message repeated several times:
Joomla Scan Python
Personality character and intelligence pdf free download 2017. Of course! Within the context of the container,
localhost means the container itself!
I was able to get this to work by specifying
--network=host. (See Use Host Networking in the Docker documentation.)
Here was the command I used (after creating a joomla database and joomla database user):
Using a Dockerized MySQL database as the backend
That was great progress! But since this was just for a temporary demo, I found an even easier way: using a MySQL Docker container as the backend database: https://hub.docker.com/_/mysql
This is what I tried the first time:
That didn’t work, though. When I started the Joomla container using the following command:
The container would soon stop. I looked at the logs using
docker logs some-joomla and found the same error message repeated numerous times:
I searched for that error message, and found a GitHub issue for another project that suggested downgrading MySQL (https://github.com/laradock/laradock/issues/1390).
It worked! I was able to access the Joomla setup on http://localhost:8080
However, I ran into an error on step 2 of the web-based Joomla setup (configuring the database):
I turns out, I had specified
localhost as the database host, as suggested. This is, of course, the same problem I had before:
localhost, on the container, is the container itself! I used the following command:
From that output I discovered that the
some-mysql container’s IP address was 172.17.0.2, which was reachable from the other container.
Unless your Docker installation is substantially different, if you start the
some-mysql container followed by the
some-joomla container, you can likely used the same IP address I did. (In my case, the some-joomla container’s IP address was the next sequential address: 172.17.0.3.)
Scanning the Joomla container
Now I had a running Joomla instance that I could target using WhatWeb and other scanners:
