PyCharm: Managing Multiple Python Versions in Ubuntu

One potential issue when running Python projects is that of conflicting versions. For instance, you may have Python 3.6 installed as the system-wide version of Python, but need to build a specific program that requires Python 3.8.

However, installing Python 3.8 as the system-wide version risks making much of your Python 3.6 code incompatible with the new version.

In this circumstance, the use of virtual environments is needed, i.e. an independent environment that runs a different Python version to the one running system-wide.

PyCharm is quite effective in serving as an IDE (Integrated Development Enviroment) for multiple Python versions. Using Ubuntu 18.04, let us see how Python 3.8 can be set up in a virtual environment through PyCharm.

Installing PyCharm

From the JetBrains website, one will see that PyCharm (at the time of writing) offers both a paid Professional version of PyCharm, as well as a free, open-source version titled Community.

By clicking Download, the file will be downloaded as a tar.gz file. At the time of writing, the file name is pycharm-community-2020.2.3.

This tar.gz file can then be extracted into a folder of your choosing:

As described in another tutorial, navigate to the bin folder and open up a terminal. PyCharm can then be installed using:

A relevant window will then open, from which the default settings for PyCharm can be customised.

Creating project in PyCharm

As mentioned, Python 3.6 is the default version of Python in this example. In the PyCharm IDE, once Create Project is selected, the below displays:

There is a dedicated tutorial on how to install python in you Opearting System. Follow the steps to install it.

Step 4 :

Now once you have done to step 3, Restart the Pycharm and select the desired interpreter in Run -> Edit Configurations inside Pycharm IDE. Now you may use this global python interpreter for the project. But in case you want to create the virtual env based on this interpreter. You may go to File -> Settings -> Project ->Project Interpreter and click on the setting icon and choose to add.

Refer to the above image and change the base Interpreter here. Here you may choose the one which is the newest you installed. Here you may choose the conda env as the Interpreter also. It is just to make sure that pycharm is fully configurable with a variety of Interpreters.

Conclusion –

This is a generic way to deal with python versioning with pycharm. It will remain same in most of the platform or operating system like mac, Linux or Windows etc. Now next to it is pycharm exploration. Just like, there are some other important configurations with pycharm like increasing memory in Pycharm and Installing packages in pycharm which we understand as next step.

Change Python Version in PyCharm

Python, like every other programming language, is maintained and updated regularly. New features are added, and changes are made with every update. Due to this, a code running on a specific Python version may not work with other versions.

PyCharm is a widely used Python IDE. We can configure Python Interpreter in the IDE to switch Python version. This tutorial will show how to achieve this.

First, we need to ensure the interpreter for the version we require is installed on PyCharm. Then, we need to select the Settings option from the File menu. From there, we need to select the Preferences option. In this, we need to select Project Interpreter . After selecting this, we will find the Python Interpreter option, and we can select the required version of the interpreter and apply the changes.

We can also change this by selecting the Edit Configurations option in the Run menu and selecting the required version in Python Interpreter .

In Pycharm 2019.1+ onwards, a new feature was added in the status bar. This feature included the version of the interpreter and seeing the version being used. We can click on this to quickly switch between different versions. If the status bar is not visible, we can use the Ctrl + Shift + A combination for Windows or the ⌘ + ⇧ + A for Mac.
