How do I create a new variable (column) in the table, using the For loop in python?

Question

There is already a column called "Imovel", I want to create a new column classifying as "House" or "Apartment"

I want to create a new column by classifying the properties according to their respective name. But he doesn't create the column, I'd like to know where I'm going. I'm learning Python.

selection = ['House', 'Beach House', 'Rest House']

def immobile():
  index = 0
  for type in data. Immovel:

if(type == selection):
      data["Type"][index] = 'House'

else:
      data["Type"][index] = 'Apartment'

index = index + 1

data.head()
