is there an itertor of chunks?

[Pedroski55]

Simple one-size

foo = [9,8,7,6,5,4,3,2,1,0]
for i in range(2, len(foo)):
    print(foo[i-2], foo[i-1], foo[i])

or variable size

chunk_size = input('How big do you like your chunks, Hunk? ')
size = int(chunk_size)
   
indexes = [j for j in range(size, 0, -1)]

for i in range(size, len(foo) + 1):
    mylist = []
    for j in indexes:
        num = i-j
        mylist.append(foo[num])
    print(mylist)
