Initializing a dictionary in python with a key value and no corresponding values
You could initialize them to None
.
Use the fromkeys
function to initialize a dictionary with any default value. In your case, you will initialize with None
since you don't have a default value in mind.
empty_dict = dict.fromkeys(['apple','ball'])
this will initialize empty_dict
as:
empty_dict = {'apple': None, 'ball': None}
As an alternative, if you wanted to initialize the dictionary with some default value other than None
, you can do:
default_value = 'xyz'
nonempty_dict = dict.fromkeys(['apple','ball'],default_value)
