Step 5: In a function called make_line, use a zero and a space to draw a line based on the size.
Hint: Use a loop:

for column in range(some_number):
  # your code here

Hint: Before the loop, create an empty string variable, and on each iteration of the loop, concatenate a zero and a space using the addition operator. Concatenation example:

line = ""
line = line + "0 "
line = line + "0 "
line = line + "0 "
print(line)
# 0 0 0
