What are the different ways to convert a generator expression to a list?

mylist = [1, 2, 3, 4, 5]
my_gen = (item for item in mylist if item > 3)
new_list = list(my_gen)

passing the generator expression to the list function is one way I learned to convert the generator expression into a list. Just curious to know if this can be in any other different way?

Solution

  • Unclear if you're looking for alternatives or just shorter.

    For shorter, you don't need an intermediate variable.

    list(item for item in mylist if item > 3)

    Which has the same effect as

    [item for item in mylist if item > 3]

    For alternatives of the generator, you could use filter function on mylist, but you'd still need list() function, or list-compression, or a while loop calling next() until the generator is exhausted for alternatives of making a list
