Explain how generator expressions can help reduce memory usage.
Consider lazy evaluation!
What does a generator expression do?
Think about how they operate in terms of memory.
True or False: Generator expressions generate all values at once.
Recall the benefits of lazy evaluation.
Design a generator expression that can filter even numbers from a range of 0 to 100, yielding their squares.
Use conditional filtering inside your expression!
You plan to iterate over a large dataset representing millions of entries. How would you implement the extraction of the first ten entries that match specific criteria using a generator expression?
Remember to count your yielded results and stop when you reach ten!
