Chaimae EL GUENNOUNI , # >>> this is when you create a new dict. you may do this with a dict comprehension like: value = 0 dict_ = {key:value for key in ["tom", "sue", "bob", "ann"]} print(dict_) # result: {'tom': 0, 'sue': 0, 'bob': 0, 'ann': 0} # >>>this is if you want to "reset" all values of an existing dict dict2 = {'tom': 7, 'sue': 4, 'bob': 0, 'ann': 2} value = 0 dict2 = {key:value for key in dict2} # result: {'tom': 0, 'sue': 0, 'bob': 0, 'ann': 0} # >>> or you can use fromkeys() dict3 = {'tom': 7, 'sue': 4, 'bob': 0, 'ann': 2} dict3 = dict3.fromkeys(dict3, 0) print(dict3)

Did you know that a dictionary can't have duplicate keys? Please tag a relevant language to improve clarity on discussion topic, by language. (Edit) Tags have been updated https://code.sololearn.com/W3uiji9X28C1/?ref=app

Yes but I want the same values of all keys not the same keys in dict

You mean change all the values of a dictionary items to zero? Idk whether a function dedicated for that purpose existed. But if not, I guess you can always resort to updating items' value using a loop right?

Chaimae EL GUENNOUNI, Provide a dictionary sample, and what result you expected. It helps us here to better understand the goal.

It has method to get all keys ( dict.keys() ). Then you can filter keys which value to be zero or any then.

x.keys() // returns all the keys of x dictionary. Then use filter to get keys having value 0

for k in d: d[k] = 0 # d dict.
