The **`partition` method** will split the first occurrence of `string_B` in `string_A` and returns a `tuple` with three items. 

* The first  item contains the part of a string the before `string_B`.

* The second item contains the `string_B` itself.

* The third item contains the part of the string after the `string_B`.

If the `string_B` is not present  in a string, then a tuple with the `string_A` and two empty strings is returned. That is, `(string_A, '', '')` is returned.

```
string_A.partition(string_B)
```

string = "this test is a test"
tup = string.partition('test')

print(tup)

## 
### Explanation 1

In the cobe above, we created a string `this test is a test` and called `partition('test')`. This will split the string at the first occurrence of the substring `test` and return a tuple containing three items. 

* First item: Part of the string before the first occurrence of `test` substring. In our case, it is `this`. 

* Second item: Separator string itself. In our case, it is a `test`. 

* Third item: Part of the string after the first occurrence of `test` substring. In our case, it is `" is a test"`.

string = "this test is a test"
tup = string.partition('best')

print(tup)

## 
### Explanation 2

In the example above, we created a string `this test is a test` and called `partition('best')`, but the string has no substring `best`, so the `partition` method will return a tuple containing three items.

* First item: Source string. In our case, `this test is a test`.

* Second and third items: Empty string.
