+### Create a Python virtual environment
+
+```bash
+python3 -m venv myenv
+source myenv/bin/activate
+# install packages, e.g.
+pip install beautifulsoup4
+```
+
+Once the virtual environment is activated, the packages installed will only be available within that environment. To exit the virtual environment use `deactivate`. To activate the environment again use `source myenv/bin/activate` in the directory where the environment was created.
