so i saw this as an answer to a question from a year ago about adding/extending a string, etc.

```
s  = 'foo'
s += 'bar'
s += 'baz'

l = []
l.append('foo')
l.append('bar')
l.append('baz')

```

my question is how would one combine these two features? l would return:

```
['foo','bar','baz']

```

but what if i wanted to add a letter to the end of each string in the list and then have it return: 

```
['food','bars','bazy']

```

is this a thing or is it more wishful thinking?
