Python Developer Interview Question:
Tell me why And When Do You Use Generators In Python?
Submitted by: MuhammadA generator in Python is a function which returns an iterable object. We can iterate on the generator object using the <yield> keyword. But we can only do that once because their values don’t persist in memory, they get the values on the fly.
Generators give us the ability to hold the execution of a function or a step as long as we want to keep it. However, here are a few examples where it is beneficial to use generators.
☛ We can replace loops with generators for efficiently calculating results involving large data sets.
☛ Generators are useful when we don’t want all the results and wish to hold back for some time.
☛ Instead of using a callback function, we can replace it with a generator. We can write a loop inside the function doing the same thing as the callback and turns it into a generator.
