Comparing Two Data frame Columns to Add a New Column With the Results

using this as a demo data set:

    a = [['11', '2'], ['15', '70'], ['8', '5']]
    df = pd.DataFrame(a, columns=['Person','one', 'two'])

    Out[8]: 
        Person one  two
    0   Jim    10  1.2
    1   John   15  70
    2   Bob    8   5 

I want to create some sort of logic calculation to compare only columns' one and two, comparing both of them and outputting a new column with the results

a calculation like this if column one is > column two put a 1 else 0

Desired output:

    Out[8]: 
        Person one  two  Results
    0   Jim    10  1.2   1
    1   John   15  70    0
    2   Bob    8   5     1
