Python | Dictionary initialization with common dictionary
Sometimes, while working with dictionaries, we might have an utility in which we need to initialize a dictionary with records values, so that they can be altered later. This kind of application can occur in cases of memoizations in general or competitive programming. Let’s discuss certain way in which this task can be performed.
Method : Using zip() + repeat()
The combination of these functions can be used to perform this particular task. In this, the Dictionary value is attached to the keys repeated using the repeat() by help of zip()
# Python3 code to demonstrate working of# Dictionary initialization with common dictionary# Using zip() + repeat()from itertools import repeat # initialization Dictionary test_dict = {'gfg' : 1, 'best' : 3} # Using zip() + repeat()# Dictionary initialization with common dictionaryres = dict(zip(range(4), repeat(test_dict))) # printing result print("The dictionary with record values : " + str(res)) |
The dictionary with record values : {0: {'gfg': 1, 'best': 3}, 1: {'gfg': 1, 'best': 3}, 2: {'gfg': 1, 'best': 3}, 3: {'gfg': 1, 'best': 3}}
