String Slicing in Python
Python slicing is about obtaining a sub-string from the given string by slicing it respectively from start to end.
Python slicing can be done in two ways.
- slice() Constructor
- Extending Indexing
slice() constructor creates a slice object representing the set of indices specified by range(start, stop, step).
- slice(start, stop, step)
start: Starting index where the slicing of object starts.
stop: Ending index where the slicing of object stops.
step: It is an optional argument that determines the increment between each index for slicing.
Return Type: Returns a sliced object containing elements in the given range only.
Index tracker for positive and negative index:
Negative comes into considers when tracking the string in reverse.

In Python, indexing syntax can be used as a substitute for the slice object. This is an easy and convenient way to slice a string both syntax wise and execution wise.
