Python: Map dictionary
Python dictionary: Exercise-70 with Solution
Write a Python program to map the values of a given list to a dictionary using a function, where the key-value pairs consist of the original value as the key and the result of the function as the value.
- Use map() to apply fn to each value of the list.
- Use zip() to pair original values to the values produced by fn.
- Use dict() to return an appropriate dictionary.
Sample Solution:
Python Code:
def test(itr, fn):
return dict(zip(itr, map(fn, itr)))
print(test([1, 2, 3, 4], lambda x: x * x))
Sample Output:
{1: 1, 2: 4, 3: 9, 4: 16}
