Tring to make automatic contact generation

Options

Below code I have made for automatic contact generation, but the problem is I have to give input as reference ID of surfaces very precisely which is time consuming. Even I go for name selection again it will create hectic in giving name. So is there any another method in which I can generate number of contacts precisely with proper formulation and settings.

frictional_ids = {761:250962,866:250945,971:250994,1076:250980,76388:251015,78078:251104}
frictional_add_off_NR = {433576:480234,433603:480434}
Damping_stablization_element = [433576,433603]
frictional_add_off_RE = {(113899,113914):433577,(72595,72600):[113789,113790],433604:[72616,72607]}
bonded_ids = {(110988,110985):[114061,114062],(111302,111299):[114054,114053],(111142,111145):[114070,114069]}
print("total number of contacts is", len(frictional_ids)+ len(bonded_ids) + len(frictional_add_off_NR) +len(frictional_add_off_RE))
