What if we need to connect two strings? Like, we have a price as a number in `price` variable, and we want to make it representatively, i.e. we want to show the price in format `n $`. This problem can be solved by concatenation.

Concatenation is joining two strings, which can be done in Python by using a simple `+` operator. It will join the string on the left side of the operator to the string on the right side. For example,

price = 25
print('Price is', str(price) + '$')

As we can see, `+` operator added the '$' sign to the `price` converted into a string.

> All the space characters are considered by `+` operator. For example, if in the example above we wrote `str(price) + ' $'` it would output `Price is 25 $`.

As a data scientist or analyst, you will have to deal with different data types. The first thing that comes to mind - is numerical data, of course. But also you will have to deal with textual data often. In this course, you will dive into strings, that represent textual data in Python, and learn how to perform different manipulations with them.

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

In this section we will learn important strings methods, like .split, .count, .strip and so on...

In this section we will learn how to format strings, learn about f-string conception, replacing particular parts of strings, splitting string by lines and so on...
