Q2. Generators in python
Ans. 
Generators in Python are functions that allow you to iterate over a sequence of items without storing them all in memory at once.
• Generators are created using a function with 'yield' instead of 'return'.

• They are used to generate a sequence of values lazily, one at a time.

• Generators are memory efficient as they do not store all values in memory at once.

• Example: def my_generator(): for i in range(5): yield i

• Example: ...read more
