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, 

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

Output:
letter i appeared 4 times in the string
letter t appeared 3 times in the string
```

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

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