U In Python

The prefix 'u' which is in front of that quote means that a Unicode string happens to built. If you need to add special characters within the string, you can do so utilizing that Python Unicode-Escape encoding. The following example reveals how:

>>> u'Hii\u0020Everyone !'

    u'Hii Everyone !'

This escape sequence \u0020 includes the Unicode character by the hexadecimal value 0x0020 (that space character) in the assigned position.
