Instead of printing a message with some variables inserted, we can save string as the pattern with `{}`, and then insert variables when needed.

To execute this, we use the same approach as for *f-strings*. For example, we can save a `pattern` as a variable. Let it be the following:
```python
pattern = "The price of {} is {} $"
```
Having such string saved, we can now use `.format` method to fill the `{}` places. If we leave these places empty, then the positional approach will be applied.

To fill the `{}` places we use `.format()` method with all the variables we want to insert from left to right. The number of `{}` blocks and variables/values within `.format` function should be the same. In our example, it should be as follows:

pattern = "The price of the {} is {} $"
print(pattern.format("laptop", 1000))
print(pattern.format("sofa", 300))

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...
