"""
You are given a string where you have to find its first word.
When solving a task pay attention to the following points:
- There can be dots and commas in a string.
- A string can start with a letter or, for example, one/multiple dot(s) or space(s).
- A word can contain an apostrophe and it's a part of a word.
- The whole text can be represented with one word and that's it.
:param text: input string
:return: str - first word of the string
