How to change python version pycharm

КАК ОБНОВИТЬ PYTHON В PYCHARM

PyCharm — это одна из наиболее популярных интегрированных сред разработки (IDE) для языков программирования Python и Ruby. Одной из важных функций PyCharm является управление версиями Python. В этой статье мы рассмотрим, как обновить версию Python в PyCharm.

Перед обновлением Python в PyCharm стоит создать виртуальное окружение (конфигурация), чтобы избежать конфликтов с текущими установленными версиями Python. Вот пример кода на Python:

python -m venv /path/to/new/virtual/environment
source /path/to/new/virtual/environment/bin/activate
pip install —upgrade pip
pip install ‘python_version’

Во второй строке кода мы активируем только что созданное виртуальное окружение. Затем мы обновляем pip, чтобы убедиться, что он актуален. Наконец, мы устанавливаем желаемую версию Python, например 3.9:

python_version=3.9
pip install python==python_version

После установки новой версии Python вы можете перезапустить PyCharm и выбрать новую версию Python в качестве интерпретатора для проекта.

Understanding PyCharm

Let’s start with PyCharm, the Swiss Army Knife of Python developers. Picture it as a toolbox, only instead of hammers and screwdrivers, you get features like intelligent code completion, on-the-fly error checking, and yes, support for multiple Python versions. PyCharm is to Python what a well-tailored suit is to James Bond: a perfect fit.

Preparing To Switch Python Versions In PyCharm

Before you dive headfirst into the Python version swap, make sure you’re in the right pool. Check your system requirements and ensure that you have the necessary Python versions installed. Picture your Python Interpreter settings as your GPS, guiding you through the Python version landscape.

Understanding Python Versions

Think of Python versions like layers of an onion — an onion with a soft, juicy core and more structured outer layers, each layer being another Python version. Each version is designed to be better than the previous one, with bugs fixed, and new features added.

What Are Python Versions?

In the realm of Python, versions are categorized by a three-part number like «3.8.5». The first number is the major version. As we journey from the center of our Python onion, each layer of the major version brings a new era of Python, introducing significant changes that might not work with older versions.

The second number is the minor version, where updates are less earth-shattering but still bring notable improvements, such as adding new functionality. It’s akin to finding an extra clove of garlic in your kitchen — it doesn’t change the dinner plan, but it can make your dish more exciting!

Finally, the third number refers to the micro version, which covers bug fixes and minor tweaks. It’s comparable to adjusting the seasoning in your recipe — it won’t drastically change the meal, but it can make it a little bit tastier.

Why Do They Matter?

Having multiple Python versions may sound confusing, and sometimes it is. It’s like juggling different cookbooks for the same dish. But this setup provides flexibility. Developers can use an older version if a particular library or framework doesn’t work with the latest version. Alternatively, they can use the newest version to take advantage of recent features and improvements.

Consider the difference between Python 2 and 3. Python 2, while still in use in some places due to legacy code, is like a trusted old cookbook. Python 3, on the other hand, is like a modern fusion cuisine recipe book, boasting features not found in Python 2.

Python versions also play a role in web design. Web developers using Python frameworks like Django or Flask need to pay attention to version compatibility to ensure their applications run smoothly.

Understanding Python versions is like understanding the ingredients in your kitchen — it helps you make informed choices about what tools to use and how to create the best possible code (or dish, in our culinary analogy!). And while it may seem a daunting task at first, it’s an integral part of your journey as a Pythonista.

Step-By-Step Guide To Changing Python Versions In PyCharm

Like attempting to bake a soufflé for the first time, changing Python versions in PyCharm can feel daunting and sprinkled with potential mishaps. Let’s look at some common problems and their solutions, to ensure your coding soufflé rises perfectly every time.

PyCharm Isn’t Detecting Your Installed Python Version

This issue is as frustrating as losing your keys when you’re already late. Often, it’s due to the path of the Python version not being included in your system’s PATH environment variable. Head over to your system settings and ensure the path to your Python version is there, like a name on a VIP list at a fancy club.

Conflicts Between Different Python Versions

Having multiple Python versions can sometimes feel like hosting a family dinner — conflicts may arise. This issue typically occurs when different versions of Python packages are installed for different versions of Python. Think of it as attempting to use the same size lid for different sized pots — it’s just not going to fit. Isolate your Python environments using virtual environments, which are like separate rooms for each Python version to chill out in, avoiding any drama.

Project Not Running With The Correct Python Version

Here you are, all set up, but your project decides to take a detour and runs on a different Python version. This is like setting your GPS for a beach vacation, but ending up at a random office building. Always double-check your project interpreter settings in PyCharm and ensure it’s pointed at the right version, like double-checking your destination before embarking on a road trip.

Trouble Installing Different Python Versions

Sometimes, the problem begins at the very start, like struggling to untie your shoelaces before a race. If you’re having trouble installing different Python versions, make sure your system meets the requirements for that version. Check the official Python documentation, your guiding star, for specific instructions.

Remember, Rome wasn’t built in a day, and your mastery over managing Python versions in PyCharm won’t happen instantly. However, with patience, resilience, and a good dollop of humor, you’ll be managing Python versions like a seasoned pro. So, go forth and conquer!

The Impact On Web Design

Now you might be thinking, «Python versions are cool and all, but what’s this got to do with my web design project?» Well, sit tight, because it’s time to connect the dots.

When you’re designing a website, your end goal is to provide an experience that’s as smooth as a well-brewed cup of coffee, with none of the bitter aftertaste. Switching Python versions in PyCharm can directly impact the success of this mission.

Catering To Different Python Libraries

Let’s start with the fact that different Python libraries and frameworks, like Django or Flask, can require different Python versions. It’s a bit like wanting to cook a specific dish but needing the right ingredients. Being adept at altering Python versions in PyCharm means you can whip up any web design «dish» you want, no matter how specific the «recipe» is.

Speed And Performance

Just like upgrading the engine in a car, using the latest Python version can potentially speed up your web development process. It allows you to take advantage of recent optimizations, improvements, and features that can make your website run faster, smoother, and provide a better user experience.

Compatibility

Imagine trying to fit a square peg into a round hole — frustrating, right? That’s what it feels like when there are compatibility issues in your project. Some parts of your web design project might be developed using different Python versions. The ability to switch between versions effortlessly ensures everything fits together seamlessly, just like a well-planned puzzle.

Future-Proofing Your Web Design Skills

The digital world is ever-evolving, much like fashion trends, and what’s in demand today might not be so tomorrow. By mastering the ability to switch Python versions, you’re not just adapting to the present requirements, but also future-proofing your skills for tomorrow’s needs. Today it’s Python 3.x, but who knows what version we’ll need in the future?

And there you have it — the impact of Python version management on web design. It’s a tool that, when wielded correctly, can supercharge your web design capabilities, much like a power-up in a video game. The world of web design awaits your enhanced Python prowess!

Upgrading pycharm venv python version

I have python 3.6 in my venv on PyCharm. However, I want to change that to Python 3.8. I have already installed 3.8, so how do I change my venv python version? I am on windows 10. Changing the version on the project intepreter settings seems to run using the new venv not my existing venv with all the packages I have installed. Attempting to add a new intepreter also results in the «OK» button being greyed out, possibly due to the current venv being not empty.

2 Answers 2

You need to create a new virtual environment with the interpreter which version is 3.8.

1. Click on «OK» => «OK»
2. Once you have set the new interpreter, PyCharm will warn you that you need update some dependencies based on your requirements.txt file or, in this case, Pipfile.lock (I am using pipenv for this project)

Kind of a dumb question, but Pycharm says I need an empty environnement location. I can do that just fine, but I want to overwrite my old python version for the current environnement location with the newest version, can this be done? I want to do this because I have my own scripts in the old environnement location and having to create a new location would mean that I would need to copy paste my scripts from the old location to the new one, which doesn’t seem right. Any thoughts on this? Thank you.
