## Updating your Venv

Earlier, we created our virtual environment (venv) and we installed
Flask and PyMySQL. Last time, we learned about `cs304dbi.py` which we
will use for the rest of the term, so we should put it in our venv so
that it's always handy:

```shell
cd ~/cs304/flask2/
ls ~/cs304/venv/lib/python3.6/site-packages/
source ~/cs304/venv/bin/activate
```

Now, run python like this:

```
python
>>> import pymysql
>>> import cs304dbi
>>> quit
```

So, that's the *before* picture. pymysql is in our venv, but not
cs304dbi. Let's do that.

```shell
cd ~/cs304/flask2/
cp ~cs304/pub/downloads/pymysql/cs304dbi.py ~/cs304/venv/lib/python3.6/site-packages/
ls ~/cs304/venv/lib/python3.6/site-packages/
```

And test:

```
python
>>> import pymysql
>>> import cs304dbi
>>> quit
```

Success? Yay!
