Lab for setting up simple python environment using venv and pip

1. Make a directory named 'simple-env' by running the command mkdir simple-env.
2. Change to this directory by running the command cd simple-env.
3. Create a virtual environment named 'env' by running the command python -m venv env.
4. Activate the virtual environment by running the command source env/bin/activate
5. Get the path for python by running which python and confirm that the path to the enabled python points to your virtual environment directory.
6. Run python -c "import pandas" to see that pandas is not installed (you should get an error).
7. Use pip to install the library pandas by running the command pip install pandas.
8. Run python -c "import pandas" again. Now you should get no output.
9. Write your environment to a file by running the command pip freeze > requirements.txt
10. See the contents of your requirements file by running cat requirements.txt. You should see some package names and versions, including a line for pandas.
