How to add a character to the end of every string in a list?

Question

Let's say I have a list: ``` list = ["word", "word2", "word3"] ``` and I want to change this list to: ``` list = ["word:", "word2:", "word3:"] ``` is there a quick way to do this?

Accepted Answer

List comprehensions to the rescue!

```
list = [item + ':' for item in list]
```

In a list of

```
['word1', 'word2', 'word3'] 
```

This will result in

```
['word1:', 'word2:', 'word3:']
```
