How to form tuple column from two columns in Pandas

Question

I\'ve got a Pandas DataFrame and I want to combine the \'lat\' and \'long\' columns to form a tuple.

Int64Index         


        

Answer 1

Get comfortable with zip. It comes in handy when dealing with column data.

df['new_col'] = list(zip(df.lat, df.long))

It's less complicated and faster than using apply or map. Something like np.dstack is twice as fast as zip, but wouldn't give you tuples.
