Welcome to the course! Strings are one of the data types, representing textual data. As a data scientist, you should be able to work with such data.

Let's start our learning with defining strings. To define a string, put text within the single (`'text'`) or double quotation marks (`"text"`). Another way - is to use the `str` function with an expression you want to represent as a string. Usually, this function is used to convert an existing variable into a string.

> Please note, that there is no difference between using single or double quotation marks. But the text within the string must be surrounded by the same type of quotation marks (i.e. you can not use `"text'`).

In this section you will be introduced with the basic concepts of strings in Python, such as creating, indexing, and slicing.
