Various programming languages become popular from year to year. This year it can be Java, last year it could be C languages. But some languages remain popular for a few years already – look at Python and Swift.
Although they differ from each other, they PYPL statistics shows that these two languages prevail.
But let’s discuss it more objectively on Python vs Swift and single out strong and weak sides of both languages.
Why is Python Popular?
Python is rather an old language that was created in 1991. Today this language is widely used for FinTech software development, AI-based software, working with Big Data, and other types of software.
It is worth noting that Python is growing fast, there are many relevant tools that enhance the language and make it much more efficient.
Companies like Netflix and Facebook actively use Python for web development, but the list of big projects is far from being full.
On the picture below you can see what is Python used more for. Let’s proceed to the main cons and pros of Python.

Strong Sides of Python
Python can boast about a few strong sides it is required to keep in mind for anybody who wants to get acquainted with this language better. Here they are.
Simplicity
Well, many young developers start using programming with Python since it is rather an easy language. Its code is simple, it can be read easily. Developers can quickly start dealing with it. Moreover, developers can even quickly understand the code written by other developers, that is also very important.
Open Source
Anyone who wants can make changes in the language code since it is an open-source language. This fact became one of the reasons for such great popularity.
High Integration Level
Python can function with many languages, that is why it is often integrated into applications created using Java or C language.
Portability
Also, if there is a necessity to change a platform, no need to change the code base, the Python-based project will surely be functioning properly.
A Large Number of Libraries
As we noted above, Python offers many libraries that can be used for different areas like machine learning or simple web app development. The most popular libraries from Python are Scikit-Learn, TensorFlow, NumPy.

Python Shortcomings
Did you hear about a fly in the ointment that always exists? We would like to note some weak sides of Python to give you a full picture.
Unfriendly to Mobile Apps
It is possible to create mobile apps using the cross-platform framework from Python, but this app won’t be a full-fledged app. It is much better to use native languages like Java/Kotlin for Android and Swift for iOS to build mobile apps.
Design Particularities
Keep in mind that some specific design restrictions are present in Python. Type of variable is usually detected automatically by Python and it leads to occasional errors from time to time. So developers should remember about it.
High Memory Consumption
Python consumes rather much memory, so it can be rather heavy and slow in some cases, and it is better to choose a lighter competitor.
More about Swift
Swift is a very young programming language since it was first released only 4 years ago. Apple built this language to replace Objective-C, and capabilities of Swift make it possible to create mobile apps faster. But first things first.
As you can understand, if this language was created by Apple, then its main goal was to create native apps for the iOS operating system as well as macOS and other devices from Apple.
Such apps like Airbnb, LinkedIn, Lyft and others are created using Swift and it is an indicator of a language’s high quality.
Last year Apple presented Swift 4 to the public, and this year 4.2 version is already available. And this is not the end, of course, Apple has far-reaching plans.
Swift Strong Sides
Swift is the language that can really astonish developers with is advantages. Check them out.
Simplicity
The same as Python, Swift’s syntax is very simple and it is its first advantage over Objective-C. Developers feel much more comfortable when they write apps using this language. They can also handle with the code written by other developers.
Fewer Bugs
All bugs can be detected before the compilation starts, Swift’s capabilities make it possible. So developers spend less time for revisions and fix all bugs in advance.
Memory Control
Memory usage in the application can be controlled using the ARC tool, and it helps distribute the memory properly. So it saves time and developers pay attention to more important tasks, so the total development time is reduced.
Open Source
Swift is also an open-source language, but unlike Python, Apple made it open source only three years ago. First, it was released as a proprietary language. When Swift appeared to be open source, its popularity started growing exponentially.
Capacity
When Swift turned into open-source language, developers added cross-platform capabilities to this language, so the total potential of Swift was increased. Now you can create apps for Linux and Windows using Swift. Many backend tools can now be combined with Swift.
What about the Disadvantages of Swift?
Despite the fact that Swift is a really amazing language, it still has some drawbacks that should be taken into account.
Lack of Skilled Developers
On the one hand, since Swift is young, there are no so many experienced developers as market demands. On the other hand, it is a profitable solution for a developer who plans to learn Swift – demand for the language is high, and high salaries can be a good motivation.
Lack of Native Libraries
Swift almost has no native libraries, especially in new versions. In some cases, it may become a serious shortcoming.
Lack of Stability
We think it is the largest disadvantage among the listed ones. If developers need to change the code base of a project written in Swift for a more fresh version of the language, they need to write code again.

Python vs Swift: What Should be Your Choice?
We have listed benefits and drawbacks of Swift and Python languages, and you may have a question “so what is better?” Well, although Swift and Python are different languages, they have something in common.
Clear syntax, lack of bugs and quick debugging are the first indicators that help these languages gain the lead.
Both Python and Swift have relevant learning tools that help beginners in software development learn programming faster and easier. You can avail online Swift & Python training beginner courses to kick start your developer journey.
At the same time, Swift has higher performance than Python can boast about. To make the picture more clear, you can check out a picture below to see the comparison of Python vs Swift.
Final Words
Drawing the line on Python vs Swift, we can summarize that everything depends on your specific requirements. Both languages can help you create first-rate software if you use it when needed. So do your best and learn – you will surely succeed!

I’ve been reading about Python, and plan to read over the coding of Swift as well. On the matter of which one is better if you want to create a true Mac executable that you open by double-clicking its icon in the Finder, which language does better? When I download programs, my face falls when I learn that you start it in the terminal rather than clicking on it. You don’t start TextEdit in the terminal. And which language can I more easily begin developing with right away by simply downloading Xcode?
Thanks.

There’s a simple rule regarding website creation: the better you want your website to be, the more it will cost. Some features like chatbots or comment sections can be optional, but the ones like Content Management System and website maintenance can be crucial. For this reason, if you want your business to run successfully, think of your website as an effective platform to represent it and not as just another budget expense.
Dear Souvik,
I enjoyed this article of yours and found it useful. Although I am 82 years old and much slowed down, I still do a little programming. I can claim breadth of perspective, having worked in 15 – 20 different programming environments (and served for a couple of years on the national standards committee for C++). I have done a small amount of programming in Python, and a lot of educational exercises in Swift. Here are a few footnotes for your article:
(1) As of the last time, I was exercising Swift (several months ago) great progress had been made on the problem of backward compatibility. My programming buddy and I were no longer tearing our hair out at every new release.
(2) I always appreciated some of the features of Python that made it attractive for the top levels of a system: readability of the code, brevity, constructive use of indenting, availability of a wide range of libraries.
(3) Swift has many great features, but let me set just one in a relationship with (2) above: If you encounter one of those rare but too-often unavoidable situations where you have to take the programming down to the bare metal, Swift will support doing so GRACEFULLY.
(4) All this leads me to wonder if there would be applications for which a good architecture would call for Python on the surface and Swift under the covers. Do you know of any such example?
