Q1. Slicing in List of Python
Ans. 
Slicing in Python allows you to extract a subset of elements from a list.
• Slicing is done using square brackets and the start:stop:step notation.

• The start index is inclusive, while the stop index is exclusive.

• You can omit any of the three parameters, defaulting to 0 for start, length of list for stop, and 1 for step.

• Negative indices can be used to slice from the end of the list.

• Example: list = [1, 2, 3, 4, 5], list[1:4]
