How can I set up a Python virtual environment in Docker?

You can set up a Python virtual environment in Docker by creating a Dockerfile that includes the necessary commands. Would you like a sample Dockerfile?

Yes, please provide a sample Dockerfile.

Here's a simple Dockerfile:

FROM python:3.9

WORKDIR /app

COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt

CMD ["python", "your_script.py"]

This sets up a Python environment and installs dependencies from requirements.txt.

How do I create the requirements.txt file?

You can create a requirements.txt file by listing your Python packages, one per line. For example:

numpy
pandas
flask
