Python change all keys of a dictionary

How do I change all keys of a dictionary

code:

d1 = {'mango':10,
          'bananna':20,
          'grapes':30}
d1_new_keys = ['yellow mango','green banana','red grapes']
d1.keys() = d1_new_keys

present answer:

SyntaxError: can't assign to function call

expected answer:

d1 = {'yellow mango': 10, 'green bananna': 20, 'red grapes': 30}

>Solution :

What you’re doing is trying to set the function d1.keys() to a list thus the error. The best way to do this would be with dictionary comprehension:

d1 = {k: v for (k, v) in zip(d1_new_keys, d1.values()}

This would essentially create a new dictionary and set it equal to d1 where the keys come from the d1_new_keys list and the values come from the original d1
