Python Generator

 Generators are useful when we want to produce a large sequence of values but we don't want to store them in memory at once

yield keyword helps python to execute generator . 

Key Features of Generators

• Memory Efficient – They do not store all values in memory; instead, they generate values one by one.
• Lazy Evaluation – Values are produced only when needed.
• Automatic State Retention – The function retains its state between yield calls.
• Iterable – Generators can be iterated using a for loop or the next() function.
