How to append elements into empty list

I am trying to append elements into empty list. using list.append() method. script gives recent value, But not appending to list.

I have tried below script it is giving updated value. 

for i in range(10):
    x = []
    if i > 1:
        x.append(i)
print (x)

Output : [9]

Expected output : [2, 3, 4, 5, 6, 7, 8, 9]

Could you please help me why i am getting this output and how to resolve it?

You should not create new list in every iteration because it replaces the old data with a new list:

x = []    
for i in range(10):
    if i > 1:
        x.append(i)
print (x)

However, there is a simpler way to do this:

[i for i in range(10) if i > 1]

Output:

[2, 3, 4, 5, 6, 7, 8, 9]
