I have a problem here, can I merge two dataframe without a key columns? For example the below, I want the result Category column on DF2 can be included on DF1, is it possible?
DF1=
id rental_name Demand Price
0 1 'Rental A' 5 50
DF2=
Category
0 'Low'
DF_merged=
id rental_name Demand Price Category
0 1 'Rental A' 5 50 'Low'
