Python

Definition¶

Python is a high-level, general-purpose programming language.

Python on Euler¶

On Euler the following versions of Python are available through modules:

Version	Module command
3.9.18	module load stack/2024-06 python/3.9.18
3.9.18 with CUDA support	module load stack/2024-06 python_cuda/3.9.18
3.10.13	module load stack/2024-06 python/3.10.13
3.11.6	module load stack/2024-06 python/3.11.6
3.11.6 with CUDA support	module load stack/2024-06 python_cuda/3.11.6
3.12.8	module load stack/2024-06 python/3.12.8

A list of the installed python packages is available here: Python_on_Euler_(Ubuntu)

Package installation¶

Pip is the package installer for Python. You can use pip to install packages from the Python Package Index and other indexes.
Conda is an open source package management system and environment management system for installing multiple versions of software packages and their dependencies.
uv is an extremely fast Python package and project manager, written in Rust.
distutils is deprecated!

You can install packages locally into "$HOME/.local" using pip via

pip install --user

or you can install them into a virtual environment, which allows for better isolation of the packages, via

python -m venv
source/bin/activate
pip install

To give the virtual environment access to the system site-packages dir, where many packages are already installed, use

python -m venv --system-site-packages

Interactive session¶

Execute "module load stack/2024-06 python/3.11.6" to makes Python available in your command line. Then "python" launches an interactive session. You should see

>>>

and you can try one of Python's easter eggs by writing

>> import this

and pressing enter.
Quit the session by writing "quit()" and enter.

Example Program¶

Create a file "hello.py", containing

print("Hello, World!")

Bring python to your command line with "module load stack/2024-06 python/3.11.6".
Run the program via

python hello.py

and the program should print

Hello, World!

to your terminal.
