Lists in List (Python)

Question

Hello Guys,

i want to initialize Lists in a List, so i want it to look like this

[[],[],...]

but i want the amount of lists in the list to have a specific length of course. Is there a faster way than to initialize the big list and then append all the small lists?

greeting and thanks for the help

You can use a list comprehension to put a certain number of elements (in this case, empty lists) into a collection

list_of_lists = [[] for _ in range(10)]
print(list_of_lists)
