Answer
fromkeys( )
Reason — fromkeys() function is used to create a new dictionary from a sequence containing all the keys and a common value, which will be assigned to all the keys.
For example:
x = ('list', 'set', 'dictionary')
y = 'mutable'
my_dict = dict.fromkeys(x, y)
print(my_dict)
Output
{'list': 'mutable', 'set': 'mutable', 'dictionary': 'mutable'}
