Why does my array lose False/empty variables?

Hey everyone, hope you are doing fine in these tumultuous times!

Edit: I found my mistake: I used 'if' instead of 'elif', therefore the code executes: is r larger than 2, if not, ArrayB = Array (which is the original array of length 10).

I have the following code, what I don't understand is that without the 'if r > 2:' part of the code, len(ArrayB) will be 20 in both cases (r =2) but with this piece of code, which is not running, len(ArrayB) becomes 10 (= losing False variables). I don't understand how why this piece of code affects the rest of my code, when r is not larger than 2?

I am running python 3.8 in Pycharm

r = 2
Array = [0,1,2,3,4,5,6,7,8,9]

if r < 1:
    ArrayB = [1] * int(r*len(Array))
    Const = len(Array)/len(ArrayB)
    for i in range(len(ArrayB)):
        ArrayB[i] = Array[int(i*Const)]

if r > 1 and r <= 2 :
    ArrayB = [False]*int(r*len(Array))
    for i in range(len(Array)):
        ArrayB[int(i*r)] = Array[i]
    print(len(ArrayB))					# First len(ArrayB)
    print(ArrayB)					# First print(ArrayB)

# if r > 2:  						#Uncomment this part and len(ArrayB) afterwards becomes 10
#     print('r is bigger than 2')
#     ArrayB = [False] * int(r * len(Array))
#     for i in range(len(Array)):
#         ArrayB[int(i*r)] = Array[i]

else:
    ArrayB = Array
print(len(ArrayB))					# Second len(ArrayB)
print(ArrayB)						# Second print(ArrayB)

output with all code active:
20
[0, False, 1, False, 2, False, 3, False, 4, False, 5, False, 6, False, 7, False, 8, False, 9, False]
10
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

output without if r >2: code:

20
[0, False, 1, False, 2, False, 3, False, 4, False, 5, False, 6, False, 7, False, 8, False, 9, False]
20
[0, False, 1, False, 2, False, 3, False, 4, False, 5, False, 6, False, 7, False, 8, False, 9, False

Thank you for your time! Edit: problem found, if statements should be elif
