====== Python virtual environment recipe ======

Note: On Ubuntu, you may need to install the ''python3-venv'' package first.

Create a setup.sh script:

<code>
#!/bin/bash

# Create virtual environment
python3 -m venv myenv

# Activate virtual environment
source myenv/bin/activate

# Upgrade pip
pip install --upgrade pip

# Install dependencies
pip install -r requirements.txt

</code>

Create a requirements.txt file:

<code>
# List your project dependencies here
package_name1
package_name2

</code>

To prepare or activate:

<code>
./setup.sh

</code>

To deactivate the virtual environment:

<code>
deactivate

</code>
