I'm stuck on constructing a **sed** expression that will parse a python file's imports and extract the names of the modules.

This is a simple example that I solved using (I need the output to be the module names without 'as' or any spaces..):

```
from testfunctions import mod1, mod2 as blala, mod3, mod4

```

What I have so far:

```
grep -ir "from testfunctions import" */*.py | sed -E s/'\s+as\s+\w+'//g | sed -E s/'from testfunctions import\s+'//g

```

This does get me the required result in a situation as above.

**The problem:**
In files where the imports are like so:

```
from testfunctions import mod1, mod2 as blala, mod3, mod4 \
     mod5, mod6 as bla, mod7 \
   mod8, mod9 ...

```

**Any ideas how I can improve my piped expression to handle multiple lines?**
