Question: For example I have a sentence 

```
"He is so .... cool!"

```

Then I remove all the punctuation and make it in a list.

```
["He", "is", "so", "", "cool"]

```

How do I remove or ignore the empty string?

Answer: 
```
>>> from string import punctuation
>>> text = "He is so .... cool!"
>>> [w.strip(punctuation) for w in text.split() if w.strip(punctuation)]
['He', 'is', 'so', 'cool']

```
```
lst = ["He", "is", "so", "", "cool"]
lst = list(filter(str.strip, lst))

```
