Q1. Convert nested list into a flat list
Ans. 
Use list comprehension to flatten a nested list into a flat list.
• Use list comprehension to iterate through the nested list and flatten it.

• Check if each element is a list, if so, iterate through it as well.

• Example: nested_list = [[1, 2, 3], [4, 5], [6], [7, 8, 9]]

• Flat list: flat_list = [item for sublist in nested_list for item in sublist]
