] | The `u` means a [`unicode`](https://docs.python.org/2/howto/unicode.html) string which should be perfectly fine to use.
But if you want to convert `unicode` to `str` (which just represents plain bytes in Python 2) then you may `encode` it using a character encoding such as `utf-8`.
```

>>> [i... | use `[str(item) for item in list]`
example
```
>>> li = [u'a', u'b', u'c', u'd']
>>> print li
[u'a', u'b', u'c', u'd']
>>> li_u_removed = [str(i) for i in li]
>>> print li_u_removed
['a', 'b', 'c', 'd']
