# Python – Difference between Uni length slicing and Access Notation

• Last Updated : 02 Sep, 2020

There are various ways to extract elements, Uni length slicing and Access Notations are among them. Let’s check difference between them.

Difference #1 : Different behaviour with Different Containers

The access notation return element in both List and Strings, but return 1 length strings while slicing using uni length slice and element in case of strings.

## Python3

Output
```The original list : [5, 7, 2, 6, 8, 1]
The original string : 572681

The access notation result for list : 6
The access notation result for string : 6

The slicing result for list : [6]
The slicing result for string : 6
```

Difference #2 : No Index out of bounds Exception in case of Slice operation

There is no out of bounds exception in case of Slice Operation, but there is, in case of access notation.

Output

The access notation result for list : list index out of range
The slicing result for list : []
```
