Write a Python program to create and display all combinations of letters, selecting each letter from a different key in a dictionary.

Sample Solution:-

Python Code:

import itertools      
d ={'1':['a','b'], '2':['c','d']}
for combo in itertools.product(*[d[k] for k in sorted(d.keys())]):
    print(''.join(combo))
	    

Sample Output:

ac
