Write a program in Python to create a dictionary from the given sequence of keys and value provided by the user

Solution

Python has predefined fromkeys() method to create a new dictionary from the given sequence of elements.

Syntax of Python fromkeys()

dictionary.fromkeys(sequence[, value])

Here, the sequence is taken as key in creating dictionary and the value parameter is taken as the value in the creating dictionary. The value is an optional parameter. It returns a new dictionary with the given sequence of elements as the keys of the dictionary.

This is the following solution to create a dictionary from the given sequence of keys and value provided by the user -

keys = {'Maths', 'English', 'Computer', 'Science'}
value = 'A'
items = dict.fromkeys(keys, value)
print items

Output of the above code

{'English': 'A', 'Maths': 'A', 'Computer': 'A', 'Science': 'A'}
