Sometimes we want to output variables with some concomitant text. For example, we want to print the sentence **"The capital of country is city"**. We can use this sentence for any pair *country-capital*, so we can use it as a template.

Surely, we can use the same approach as before: print each string/variable, separated by a comma. But it's a bit irrational, isn't it? One of the ways of simplifying is using **f-strings**. They allow you to print strings with variables within single pair of quotes.

Let's consider the syntax. All the text we intend to print should be placed within quotes preceded by symbol `f`, and all the variables you want to print inside this text should be enclosed with curly brackets. For example,

weight = 70
unit = 'kg'
print(f"The weight is {weight} {unit}.")

As can seen, there are no redundant commas or quotes. Looks more convenient.

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...
