Let's consider some other methods that can be applied to strings. One of them can help us count the number of appearances of some symbol/substring within a string.

To count the number of symbol/substring in string use `.count(symbol/substring)` method. For example, 

string = "String Manipulation in Python"
print("letter i appeared", string.count('i'), "times in the string.")
print("letter t appeared", string.count('t'), "times in the string.")

> Note
>
> This method is case-sensitive to symbols. For the example above, `string.count('m')` will return 0, while `string.count('M')` will return 1.

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...
