I have a Pandas Dataframe with a column that looks like this:
Car_Make
0 2017 Abarth 124 Spider ManualConvertible
1 2017 Abarth 124 Spider AutoConver
Is this what you are looking for:
df.car_make.str.rsplit(' ', 1, expand=True)
# returns:
0 1
0 2017 Abarth 124 Spider ManualConvertible
1 2017 Abarth 124 Spider AutoConvertible
2 2017 Abarth 124 Spider ManualConvertible
3 2017 Abarth 124 Spider AutoConvertible
4 2017 Abarth 595 ManualHatch
5 2017 Abarth 595 AutoHatch
