Hello, I don’t think you need to print each number separately.
Try to use str.join() to join them into a string, and then print it all
at once.

For example:

a = list(range(6))         # a == [0, 1, 2, 3, 4, 5]
s = " ".join(map(str,a))   # s == '0 1 2 3 4 5'
print(s)

Note that join can only operate on lists where all elements are strings,
so map(str, list) is used here to convert all elements into strings.
