- [Narrator] Generator expressions are another way…in which a generator object can be constructed.…It's a little bit different…and a little bit more concise…than writing a generator function.…Generator expressions can be very powerful.…This is an example of a list comprehension.…Generator expressions are almost identical…to list comprehensions in terms of syntax.…I've pulled up 01_03\list_comprehension…from the Exercise Files to show the differences.…A list comprehension is simply an expression…with a set of brackets which evaluates to a list.…

The only syntax difference between list comprehensions…and generator expressions is the use of parentheses…rather than brackets.…The bigger difference is what they return.…A generator expression evaluates to a generator object…rather than a list.…As you would expect with a generator object,…it only evaluates one item at a time…without storing any sequence in memory.…Let's take a look at an example.…In the previous video, we built a generator function…to produce even integers.…
