To go through these exercises, you need to create a new folder on your Desktop called bobiac_uv.

Exercise 1#

Step 1#

Create a Python Environment with uv and Install numpy & matplotlib

  1. Open the Terminal or PowerShell and navigate to the bobiac_uv folder.

  2. Create a new virtual environment with uv in the bobiac_uv_env folder named .venv.

  3. Activate the newly created .venv virtual environment.

  4. Install numpy and matplotlib in the .venv virtual environment.

  5. List the installed packages in the .venv virtual environment to confirm that numpy and matplotlib are installed.

  6. Deactivate the .venv virtual environment.

Solution

  1. open the Terminal or PowerShell.

  2. cd .../Desktop/bobiac_uv

  3. uv venv .venv (or simply uv venv)

  4. source .venv/bin/activate (Linux/macOS) or .venv\Scripts\activate (Windows)

  5. uv pip install numpy matplotlib

  6. uv pip list

  7. deactivate

Step 2#

Add to the environment created in Step 1 the scikit-image package

  1. Open the Terminal or PowerShell and navigate to the bobiac_uv folder.

  2. Activate the .venv virtual environment created in Step 1.

  3. Add the scikit-image package to the .venv virtual environment.

  4. List the installed packages in the .venv virtual environment to confirm that scikit-image is installed.

  5. Deactivate the .venv virtual environment.

Solution

  1. open the Terminal or PowerShell.

  2. cd .../Desktop/bobiac_uv

  3. source .venv/bin/activate (Linux/macOS) or .venv\Scripts\activate (Windows)

  4. uv pip install scikit-image

  5. uv pip list

  6. deactivate

Exercise 2#

Create a .py file with the PEP723 ///script header using uv

  1. Open the Terminal or PowerShell and navigate to the bobiac_uv folder.

  2. Inside the bobiac_uv folder, create a new folder named py_folder and navigate into it.

  3. Use uv to create a new Python file named bobiac_script.py with the PEP723 ///script header and Python 3.13.

  4. Add numpy and matplotlib as dependencies to the bobiac_script.py file using uv.

  5. Run the bobiac_script.py file using uv to verify that the dependencies are installed and the script runs without errors.

  6. Optional: show the dependencies of the bobiac_script.py file using uv tree.

  7. Optional: show the python version used for the bobiac_script.py file using uv python.

Solution

  1. open the Terminal or PowerShell.

  2. cd .../Desktop/bobiac_uv

  3. mkdir py_folder

  4. cd .../Desktop/bobiac_uv/py_folder

  5. uv init --script bobiac_script.py -p 3.13

  6. uv add --script bobiac_script.py numpy matplotlib

  7. uv run bobiac_script.py

  8. Optional: uv tree --script bobiac_script.py

  9. Optional: uv python find --script bobiac_script.py --show-version
