How to create expression that returns 1,12,123,1234 in Python

Navigation
1

I'm learning the basics of python and I came across an exercise where I have to build the following sequence: 

1   
12  
123  
1234  
12345  
123456  
1234567  
12345678  
123456789

I think it's a simple thing to do, but can anyone help me?

The code is very simple: 

st = ''
for i in range(1, 10):
    st += str(i)
    print st

You can use a loop that has the minimum value and rotate as long as it is smaller and / or equal to the maximum value and print the value before incrementing.
