how to compute a new column based on the values of other columns in pandas - python

Question

Let\'s say my data frame contains these data:

>>> df = pd.DataFrame({\'a\':[\'l1\',\'l2\',\'l1\',\'l2\',\'l1\',\'l2\'],
                       \'b\'         


        

Answer 1

You can also use the string methods.

df['c'] = (df.a.str[-1] == df.b).astype(int)
