# Double each value in the dictionary
double_dict1 = {k:v*2 for (k,v) in dict1.items()}
# double_dict1 = {'e': 10, 'a': 2, 'c': 6, 'b': 4, 'd': 8} <-- new dict

Example 2: types of dict comprehension

# Dictionary Comprehension Types

{j:j*2 for i in range(10)}

#using if 
{j:j*2 for j in range(10) if j%2==0}

#using if and 
{j:j*2 for j in range(10) if j%2==0 and j%3==0}

#using if else
{j:(j*2 if j%2==0 and j%3==0 else 'invalid' )for j in range(10) }
