Python generator comprehensions are a way of creating generator objects from existing iterables, such as lists, tuples, strings, etc. They are similar to list comprehensions, but instead of creating a new list in memory, they create a generator that can yield one element at a time on demand. Generator comprehensions can save memory and improve performance when you only need to process one element at a time from a large or infinite sequence. The syntax of a generator comprehension is: where: Here is an example of a generator comprehension: Notice…
