Trying to create new tuple column on pandas

Question

I'm trying to create a new column, a tuple based on two existing columns:

dff['net_sys']= dff[['network', 'syscode']].apply(lambda x: (x['network'], x['syscode']),axis=1)

I'm getting an error:

TypeError: list indices must be integers or slices, not list

Answer 1

Using

dff['net_sys']= dff[['network', 'syscode']].apply(tuple,axis=1)

Or

dff['net_sys']=list(zip(dff['network'],dff['syscode']))
