Initializing a dictionary in python with a key value and no corresponding values

Question

I was wondering if there was a way to initialize a dictionary in python with keys but no corresponding values until I set them. Such as:

Definition = {\'apple\':         


        

Answer 1

You can initialize the values as empty strings and fill them in later as they are found.

dictionary = {'one':'','two':''}
dictionary['one']=1
dictionary['two']=2
